Additional Information

This does not occur with slow scrolling down. It might have something to do with "momentum" of a faster scroll propelling it to the bottom that's not getting caught by the onscroll event handler (onScroll in watch-video-live-chat.js). I can tell that this is the likely issue because it's not happening when I put that handler logic in a setTimeout with a 100ms delay. That would technically work, but I would like to see if there's a less hacky fix.

My bad lol! I searched for "live arrow" and thought, well, certainly that should be enough to find any instances if there were any
