Original issue's description:
> Enable a11y audit for chrome://settings
>
> Enabled the tests and fixed failure. Failure was due to transition obscuring elements in the UI.
>
> Another failure was caused because there were no labels on the mic and camera drop downs.
>
> Another failure was that there was no captions for a video element. This is used to capture a profile picture in chrome OS, so there wouldn't be any captions. This element is ignored in the a11y audit.
>
> There was also an issue with the dispatching of events in the ensureTransitionEndEvent function that wouldn't allow the event to bubble.
