Fix expanded video player issues (#13541)

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.
