## Issue
Fixes 4460 `unmuted state lost / reverted`
1. Play a video.
2. Press mute.
3. Drag the volume bar to unmute.
4. Play a new video --> the video starts muted.
## Fix
The `volumechange` handler was comparing against stale variables, so there are times where the state was not saved. Just save both `muted` and `volume` without additional gating (the gating is probably unnecessary in the first place, since we are in a onChange function).
