Safari: YouTube videos auto-play after tab events or wake.

Safari 27: Paused Youtube videos may randomly start playing when other tabs are reloaded, Youtube videos in other tabs are played, or computer wakes from sleep.

Does not seem to be any pattern to which other Youtube tab plays, or when. Started after upgrade to Safari 27

Same problem with me too, but on Safari 26.5. Youtube videos buried in my open tabs randomly play, forcing me to go on a bug hunt or it will autoplay the next videos forever. I haven't found any trigger. Been driving me nuts for 6mos or more. All autoplay disabled in Settings.
