Add imperative access to popover invoker, and connect popover/invoker to implicit anchor element #10728

mfreed7 · 2024-10-28T23:46:29Z

This includes two related changes:

The showPopover() and togglePopover() methods now include an options bag that allows setting the popover invoker implicitly. Previously this was only possible via the declarative popovertarget attribute.
Popover invokers (set declaratively or imperatively) now create an implicit anchor element reference for that popover.

This new behavior was resolved in the WHATWG/CSSWG/OpenUI joint task force meeting on June 26, 2024.

Closes #10442
Closes #10675

At least two implementers are interested (and none opposed):
- Chromium
- This behavior was resolved in the WHATWG/CSSWG/OpenUI joint task force meeting on June 26, 2024.

Normative behavior looks good. A variety of editorial tweaks.

Thanks for the quick review! I think I got everything, LMK if I missed something.

Editorially LGTM (with one more nit). Let us know when all the boxes are checked.

Thanks! Done. It would be good to get the attention of @annevk and @smaug----, since the implementer support checkbox relies on our joint resolution at the form controls task force. (And I therefore didn't want to clutter up the standards positions requests for this.)

@mfreed7 OP doesn't include a link to a PR for renaming the tests away from .tentative. Have the tests also been updated to test source instead of invoker?

https://chromium-review.googlesource.com/c/chromium/src/+/6025803

There seems to be a chicken and egg problem with this. I've had folks complain about renaming .tentative too early (before the spec PR lands) and too late (after the spec PR lands).

Have the tests also been updated to test source instead of invoker?

There seems to be a chicken and egg problem with this.

Ideally you create a PR against web-platform-tests that the specification editors can merge. That's how we have done this thus far.

The spec PR landed: whatwg/html#10728 so this removes .tentative from the WPTs. Bug: 364669918 Change-Id: I35e50fff8d94ff52e212844814a4e597c35d78b4

Yeah, ok. The Chromium process makes that a bit harder, since we're accustomed to doing the review for WPT stuff within our code review system, and it then gets pushed automatically. I don't know if there's an easy way to tell it not to merge the WPT PR when the Chromium PR gets merged. If you know of one, please let me know!

mfreed7 · 2024-11-18T17:36:48Z

You don't have to use the Chromium process to create a WPT PR. You can just create a PR directly against the repo.

Yeah. It's just a lot more work. 😄

That seems strange. It really shouldn't be.

That seems strange. It really shouldn't be.

Only due to familiarity. I spend 99% of my time writing C++ code within Chromium's tooling, so venturing outside is painful. It's ok - I'll try to put up the rename PRs like this in the future.

FWIW, similar here. Writing wpts is quite a bit easier on mozilla-central vs dealing with wpt repository explicitly.
