Bug 1986710 [wpt PR 54668] - Make ESC lose interest in all elements that have interest, a=testonly

Automatic update from web-platform-tests
Make ESC lose interest in all elements that have interest

This CL implements the behavior described in the spec PR:

whatwg/html#11006

That is: the ESC key is handled very much like popovers - the
focus doesn't need to be on the invoker for ESC to work. Also,
hitting ESC loses interest in all elements that currently
have interest, in reverse order. A test is added to confirm this.

Note: I purposely did not use close watcher here, since I don't
believe the close watcher stack should get involved. E.g. the
android Back button should just navigate back, and not first lose
interest in things. Closing a popover or modal dialog is different
than a tooltip being open on a page.
