@gibson042 BTW, I copied this from other similar assertions but... what is GAP?

My attempt to make clear that this is not a true passing assertion, but rather a failure to verify the desired assertion at all... a gap between intent and capability.

Ah. Since it’s all uppercase, I thought it’s an acronym. 😅

… document The `doc` variable in: https://github.com/jquery/jquery/blob/3.4.1/src/event/focusin.js#L30 matched `document` for `document` & `window` for `window`, creating two separate wrapper event handlers & calling handlers twice if at least one `focusout` or `focusin` handler was attached on *both* `window` & `document`, or on `window` & another regular node. Also, fix the "focusin from an iframe" test to actually verify the behavior from commit 1cecf64 - the commit that introduced the regression - to make sure we don't regress on either front.

Backport tests from a jQuery 3.x fix that's not needed on `master`. Also, fix the "focusin from an iframe" test to actually verify the behavior from commit 1cecf64 - the commit that introduced the regression - to make sure we don't regress on either front. The main part of the modified test was checking that focusin handling in an iframe works and that's still checked. The test was also checking that it doesn't propagate to the parent document, though, and, apparently, in IE it does. This one test is now blacklisted in IE. (cherry picked from 9e15d6b) (cherry picked from 1a4f10d) Ref jquerygh-4652 Ref jquerygh-4656
