Gonna leave my last comment on #13162 to be discussed here too, in case any reviewer misses it.

I have been reconsidering part of my understanding of this problem, though. To use yours PR description, I think that to...

Remove existing comment replies screens before adding new one.

... is absolutely great and solve the annoying problem with infinite back-pages, but I'm not sure that to...

Also close all comment replies screens when the video details screen is closed.

... is ideal anymore. Reason being that closing the replies' page that the user has on screen may be a little disconcerting, cause, sure, the user may not want to watch/listen to the video anymore, but they may still be reading the comments on screen.
