When using `obj.play()` on an audio (mp3) component, the second time .play() is called, the full audio clip does not play.

Oh, wait. The problem I was experiencing, where the second play didn't play all of the 2 second clip, has stopped occurring. So its not a straight black and white "it doesn't work the second time" There seems to be something else going on.  I'll update this ticket if the problem occurs again, or close it if the problem does not occur again in the next day or so.

Nope the problem is back. The second (and following times) I press play, the first half a second or so is cut off. Still not sure why its intermittent.

The fix for this issue needs to be made outside of the WebKit source code, therefore marking this as "RESOLVED | MOVED".

The work on that operating system component is being done under this radar:

We believe this is resolved in:
macOS Ventura Beta 2 (and newer).
iOS 16.0 Beta 2 (and newer).
