Feature request: Fix Subtitle List Please (Animated GIF attached)

Netflix - Google Chrome 2020-10-11 09-11-07_3

I usually use subtitle list with ctrl+mouse wheel zoom-in because main screen doesn’t show me a full sentence because a sentence is splitted by subtitle unit.
The problem is when I click a subtitle or while video play goes over to next subtitle, the subtitle list scrolls by itself and it bothers and distracts my practice.
So I ask the developer to stop this unnecessary auto-scroll.
Also, I ask the developer to make a shortcut to hide subtitles on subtitle list for listening practice or memorizing.
