Affects Safari 16.5+

If user increases the volume of an autoplaying video (started muted) with custom volume slider, the video stops playback. Probably an autoplay with sound prevention.

Minimal repro: https://stackblitz.com/edit/stackblitz-starters-revjx7?file=public%2Findex.html

Expected behavior: The video continues playing and the volume increases.

Please try to reproduce in a recent STP build.

I couldn't reproduce it with the STP 176. It is working as expected.
