Fixes#13536
- Expanding a paused video doesn't autoplay anymore
- Default volume level for the expanded video inherited from the original video
Position/playing state/volume are carried over from the original video player
to the modal, but they're not reported back to the modal as it would require
deeper changes.
* Add some explanation to the mute modal dialog
* Remove `isSubmitting` from mute modal code, this wasn't used
* Refactor block modal
