YouTube will literally resume back to exactly where I was, then seemingly noticing that I switched back to it, go ahead and close the video I was watching. With all sorts of animations too, it's not just a case of having showed a cached screenshot. YouTube seems to intentionally forget where in a video I was, often after having been paused in the background for only a minute or two.

Why??

See if turning off your ad blocker makes a difference. I've noticed that sometimes YouTube has parts of the site the apparently can look to ad blockers like they are part of an ad (maybe intentionally to annoy people with ad blockers?).

Likely some kind of complex refresh operation that kicks off when entering the foreground and takes a few seconds to complete before overwriting your state.

YouTube on TVs will often keep closed captioning on when switching accounts, then notice that CC is on and turn it off. Even though every account in the household always has CC turned on.
