Is this fixed already? I can't reproduce it in dev build

Hi @predystopic-dev sorry for the delayed response. I can still replicate this on my end.

I can specifically replicate this by pressing the scrollbar in the UI, but not by scrolling with my mouse.

My analysis from re-discovering this myself:

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.
