Bug 1810012 [wpt PR 37915] - Add aftertoggle event for popover, a=t…

…estonly Automatic update from web-platform-tests Add `aftertoggle` event for popover This CL adds an async `aftertoggle` event to both the show and hide popover transitions, and renames the event class from BeforeToggle to PopoverToggle, to be used by both events. This was resolved by OpenUI here: openui/open-ui#342 (comment) Bug: 1307772 Change-Id: I996be74b90f43eee4bf859cecfed051fa6f633d5 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/4160443 Auto-Submit: Mason Freed <[email protected]> Commit-Queue: Joey Arhar <[email protected]> Commit-Queue: Mason Freed <[email protected]> Reviewed-by: Joey Arhar <[email protected]> Cr-Commit-Position: refs/heads/main@{#1092158} -- wpt-commits: e3246afc19a62a2d4f26786e6eae72a601a2c032 wpt-pr: 37915
