Nightly from a few days ago.


- Open a video, e.g. (doesn't matter if it's embedded or direct)

- Start it playing, click the speaker icon to mute

- Click on the time bar to seek to another time

- Video becomes unmuted, though the speaker icon still shows 0.  You have to click it twice to get it to mute again.

- Seek again, it becomes unmuted.

Expected results:

Video should stay muted after seeking.
