Forces the YouTube Studio background to be dark immediately to prevent the page from a white flash on reload. This is very annoying to the eyes especially when using dark mode in a dark room.

Avoids getting flashbanged with a completely white screen multiple times when refreshing the page.
This gets extremely annoying especially when managing a channel with shorts and it's not updating properly.

I've reported this bug using the creator feedback form but got the reply that they won't fix it because I'm not using Chrome as a browser.
