Risk Assessment
What approach did you choose and why?
I removed our handling of the
focusout
event and replaced it with code that handles events from the<include-fragment-element>
to focus the first element after deferred content has loaded.Anything you want to highlight for special attention from reviewers?
I discovered the issue was that we were improperly handling the
focusout
event by using it to close the popover. This code was part of the original component built by the a11y team, so I fear I may have removed important functionality. Removing it however does not cause any tests to fail, so I assume we're good, but I need someone familiar with that old code to examine this PR carefully.Accessibility
