HTML #named-access-on-the-window-object

This patch implements [named access on the window object](https://html.spec.whatwg.org/#named-access-on-the-window-object) based on @pylbrecht’s and @yvt’s previous work (see also #27952, #25562, #21869, #19904).

That work makes 130 tests pass, and I’ve made some additional changes to make [the test for the feature itself](https://wpt.live/webidl/ecmascript-binding/window-named-properties-object.html) pass too, but I haven’t worked with mozjs before, so I have no idea if I’ve gone about my changes the Right Way.

In particular, this patch:

* [x] applies @pylbrecht’s patch (#27952)
* [x] resolves conflicts related to #29079 and #28546 (5ae0ca4)
* [x] applies @yvt’s patch to the segfault in getPrototypeIfOrdinary (1e24ffd)
* [x] reverts the change introducing Untransplantable (76dc35a), since #28534 was abandoned in favour of #28536
* [x] triages the unexpected WPT results, updating expectations as needed (see below)
* [x] fixes the failures in /webidl/ecmascript-binding/window-named-properties-object.html (3844f69)
    * [x] fixes the failures in the [[GetOwnProperty]] subtest (75c24e9)
    * [x] fixes the failures in the [[DefineOwnProperty]] subtest (e4e7a14)
    * [x] fixes the failures in the [[HasProperty]] subtest (75c24e9)
    * [x] fixes the failures in the [[Get]] subtest (4bafb27)
    * [x] fixes the failures in the [[Set]] (direct) subtest (e4e7a14)
    * [x] fixes the failures in the [[Delete]] subtest (4bafb27)
    * [x] fixes the failures in the [[OwnPropertyKeys]] subtest (afcd24a)
* [x] resolves the todos and fixmes
    * [x] Document: handle exposed objects ×3 (ed3e37b)
    * [x] Window::NamedGetter: document.get_elements_with_id() (618ef57)
    * [x] get_own_property_descriptor: check for interactions with indexed access (b906fae)
    * [x] create trap: pass proper classp (618ef57)

HTML #named-access-on-the-window-object

This patch implements [named access on the window object](https://html.spec.whatwg.org/#named-access-on-the-window-object) based on @pylbrecht’s and @yvt’s previous work (see also #27952, #25562, #21869, #19904).

That work makes 130 tests pass, and I’ve made some additional changes to make [the test for the feature itself](https://wpt.live/webidl/ecmascript-binding/window-named-properties-object.html) pass too, but I haven’t worked with mozjs before, so I have no idea if I’ve gone about my changes the Right Way.

In particular, this patch:

* [x] applies @pylbrecht’s patch (#27952)
* [x] resolves conflicts related to #29079 and #28546 (5ae0ca4)
* [x] applies @yvt’s patch to the segfault in getPrototypeIfOrdinary (1e24ffd)
* [x] reverts the change introducing Untransplantable (76dc35a), since #28534 was abandoned in favour of #28536
* [x] triages the unexpected WPT results, updating expectations as needed (see below)
* [x] fixes the failures in /webidl/ecmascript-binding/window-named-properties-object.html (3844f69)
    * [x] fixes the failures in the [[GetOwnProperty]] subtest (75c24e9)
    * [x] fixes the failures in the [[DefineOwnProperty]] subtest (e4e7a14)
    * [x] fixes the failures in the [[HasProperty]] subtest (75c24e9)
    * [x] fixes the failures in the [[Get]] subtest (4bafb27)
    * [x] fixes the failures in the [[Set]] (direct) subtest (e4e7a14)
    * [x] fixes the failures in the [[Delete]] subtest (4bafb27)
    * [x] fixes the failures in the [[OwnPropertyKeys]] subtest (afcd24a)
* [x] resolves the todos and fixmes
    * [x] Document: handle exposed objects ×3 (ed3e37b)
    * [x] Window::NamedGetter: document.get_elements_with_id() (618ef57)
    * [x] get_own_property_descriptor: check for interactions with indexed access (b906fae)
    * [x] create trap: pass proper classp (618ef57)

HTML #named-access-on-the-window-object

This patch implements [named access on the window object](https://html.spec.whatwg.org/#named-access-on-the-window-object) based on @pylbrecht’s and @yvt’s previous work (see also #27952, #25562, #21869, #19904).

That work makes 130 tests pass, and I’ve made some additional changes to make [the test for the feature itself](https://wpt.live/webidl/ecmascript-binding/window-named-properties-object.html) pass too, but I haven’t worked with mozjs before, so I have no idea if I’ve gone about my changes the Right Way.

In particular, this patch:

* [x] applies @pylbrecht’s patch (#27952)
* [x] resolves conflicts related to #29079 and #28546 (5ae0ca4)
* [x] applies @yvt’s patch to the segfault in getPrototypeIfOrdinary (1e24ffd)
* [x] reverts the change introducing Untransplantable (76dc35a), since #28534 was abandoned in favour of #28536
* [x] triages the unexpected WPT results, updating expectations as needed (see below)
* [x] fixes the failures in /webidl/ecmascript-binding/window-named-properties-object.html (3844f69)
    * [x] fixes the failures in the [[GetOwnProperty]] subtest (75c24e9)
    * [x] fixes the failures in the [[DefineOwnProperty]] subtest (e4e7a14)
    * [x] fixes the failures in the [[HasProperty]] subtest (75c24e9)
    * [x] fixes the failures in the [[Get]] subtest (4bafb27)

HTML #named-access-on-the-window-object

This patch implements [named access on the window object](https://html.spec.whatwg.org/#named-access-on-the-window-object) based on @pylbrecht’s and @yvt’s previous work (see also #27952, #25562, #21869, #19904).

That work makes 130 tests pass, and I’ve made some additional changes to make [the test for the feature itself](https://wpt.live/webidl/ecmascript-binding/window-named-properties-object.html) pass too, but I haven’t worked with mozjs before, so I have no idea if I’ve gone about my changes the Right Way.

In particular, this patch:

* [x] applies @pylbrecht’s patch (#27952)
* [x] resolves conflicts related to #29079 and #28546 (5ae0ca4)
* [x] applies @yvt’s patch to the segfault in getPrototypeIfOrdinary (1e24ffd)
* [x] reverts the change introducing Untransplantable (76dc35a), since #28534 was abandoned in favour of #28536
* [x] triages the unexpected WPT results, updating expectations as needed (see below)
* [x] fixes the failures in /webidl/ecmascript-binding/window-named-properties-object.html (3844f69)
    * [x] fixes the failures in the [[GetOwnProperty]] subtest (75c24e9)
    * [x] fixes the failures in the [[DefineOwnProperty]] subtest (e4e7a14)
    * [x] fixes the failures in the [[HasProperty]] subtest (75c24e9)
    * [x] fixes the failures in the [[Get]] subtest (4bafb27)
    * [x] fixes the failures in the [[Set]] (direct) subtest (e4e7a14)
    * [x] fixes the failures in the [[Delete]] subtest (4bafb27)
    * [x] fixes the failures in the [[OwnPropertyKeys]] subtest (afcd24a)
* [x] resolves the todos and fixmes
    * [x] Document: handle exposed objects ×3 (ed3e37b)
    * [x] Window::NamedGetter: document.get_elements_with_id() (618ef57)
    * [x] get_own_property_descriptor: check for interactions with indexed access (b906fae)
    * [x] create trap: pass proper classp (618ef57)

HTML #named-access-on-the-window-object

This patch implements [named access on the window object](https://html.spec.whatwg.org/#named-access-on-the-window-object) based on @pylbrecht’s and @yvt’s previous work (see also #27952, #25562, #21869, #19904).

That work makes 130 tests pass, and I’ve made some additional changes to make [the test for the feature itself](https://wpt.live/webidl/ecmascript-binding/window-named-properties-object.html) pass too, but I haven’t worked with mozjs before, so I have no idea if I’ve gone about my changes the Right Way.

In particular, this patch:

* [x] applies @pylbrecht’s patch (#27952)
* [x] resolves conflicts related to #29079 and #28546 (5ae0ca4)
* [x] applies @yvt’s patch to the segfault in getPrototypeIfOrdinary (1e24ffd)
* [x] reverts the change introducing Untransplantable (76dc35a), since #28534 was abandoned in favour of #28536
* [x] triages the unexpected WPT results, updating expectations as needed (see below)
* [x] fixes the failures in /webidl/ecmascript-binding/window-named-properties-object.html (3844f69)
    * [x] fixes the failures in the [[GetOwnProperty]] subtest (75c24e9)
    * [x] fixes the failures in the [[DefineOwnProperty]] subtest (e4e7a14)
    * [x] fixes the failures in the [[HasProperty]] subtest (75c24e9)
    * [x] fixes the failures in the [[Get]] subtest (4bafb27)
    * [x] fixes the failures in the [[Set]] (direct) subtest (e4e7a14)
    * [x] fixes the failures in the [[Delete]] subtest (4bafb27)
    * [x] fixes the failures in the [[OwnPropertyKeys]] subtest (afcd24a)
* [x] resolves the todos and fixmes
    * [x] Document: handle exposed objects ×3 (ed3e37b)
    * [x] Window::NamedGetter: document.get_elements_with_id() (618ef57)
    * [x] get_own_property_descriptor: check for interactions with indexed access (b906fae)
    * [x] create trap: pass proper classp (618ef57)

HTML #named-access-on-the-window-object

This patch implements [named access on the window object](https://html.spec.whatwg.org/#named-access-on-the-window-object) based on @pylbrecht’s and @yvt’s previous work (see also #27952, #25562, #21869, #19904).

That work makes 130 tests pass, and I’ve made some additional changes to make [the test for the feature itself](https://wpt.live/webidl/ecmascript-binding/window-named-properties-object.html) pass too, but I haven’t worked with mozjs before, so I have no idea if I’ve gone about my changes the Right Way.

In particular, this patch:

* [x] applies @pylbrecht’s patch (#27952)
* [x] resolves conflicts related to #29079 and #28546 (5ae0ca4)
* [x] applies @yvt’s patch to the segfault in getPrototypeIfOrdinary (1e24ffd)
* [x] reverts the change introducing Untransplantable (76dc35a), since #28534 was abandoned in favour of #28536
* [x] triages the unexpected WPT results, updating expectations as needed (see below)
* [x] fixes the failures in /webidl/ecmascript-binding/window-named-properties-object.html (3844f69)
    * [x] fixes the failures in the [[GetOwnProperty]] subtest (75c24e9)
    * [x] fixes the failures in the [[DefineOwnProperty]] subtest (e4e7a14)
    * [x] fixes the failures in the [[HasProperty]] subtest (75c24e9)
    * [x] fixes the failures in the [[Get]] subtest (4bafb27)
    * [x] fixes the failures in the [[Set]] (direct) subtest (e4e7a14)
    * [x] fixes the failures in the [[Delete]] subtest (4bafb27)
    * [x] fixes the failures in the [[OwnPropertyKeys]] subtest (afcd24a)
* [x] resolves the todos and fixmes
    * [x] Document: handle exposed objects ×3 (ed3e37b)
    * [x] Window::NamedGetter: document.get_elements_with_id() (618ef57)
    * [x] get_own_property_descriptor: check for interactions with indexed access (b906fae)
    * [x] create trap: pass proper classp (618ef57)

HTML #named-access-on-the-window-object

This patch implements [named access on the window object](https://html.spec.whatwg.org/#named-access-on-the-window-object) based on @pylbrecht’s and @yvt’s previous work (see also #27952, #25562, #21869, #19904).

That work makes 130 tests pass, and I’ve made some additional changes to make [the test for the feature itself](https://wpt.live/webidl/ecmascript-binding/window-named-properties-object.html) pass too, but I haven’t worked with mozjs before, so I have no idea if I’ve gone about my changes the Right Way.

In particular, this patch:

* [x] applies @pylbrecht’s patch (#27952)
* [x] resolves conflicts related to #29079 and #28546 (5ae0ca4)
* [x] applies @yvt’s patch to the segfault in getPrototypeIfOrdinary (1e24ffd)
* [x] reverts the change introducing Untransplantable (76dc35a), since #28534 was abandoned in favour of #28536
* [x] triages the unexpected WPT results, updating expectations as needed (see below)
* [x] fixes the failures in /webidl/ecmascript-binding/window-named-properties-object.html (3844f69)
    * [x] fixes the failures in the [[GetOwnProperty]] subtest (75c24e9)
    * [x] fixes the failures in the [[DefineOwnProperty]] subtest (e4e7a14)
    * [x] fixes the failures in the [[HasProperty]] subtest (75c24e9)
    * [x] fixes the failures in the [[Get]] subtest (4bafb27)
    * [x] fixes the failures in the [[Set]] (direct) subtest (e4e7a14)
    * [x] fixes the failures in the [[Delete]] subtest (4bafb27)
    * [x] fixes the failures in the [[OwnPropertyKeys]] subtest (afcd24a)
* [x] resolves the todos and fixmes
    * [x] Document: handle exposed objects ×3 (ed3e37b)
    * [x] Window::NamedGetter: document.get_elements_with_id() (618ef57)
    * [x] get_own_property_descriptor: check for interactions with indexed access (b906fae)
    * [x] create trap: pass proper classp (618ef57)
