Thanks for putting in the effort to make this a reality, I was about to do it because I noticed YouTube fails to remember the dark mode setting. Just an observation in case you are unaware the specific paper toggle for the dark mode (if you can find a unique identifier for it) can be easily edited by adding the "checked" property. This should enable the dark mode.
I'm glad someone did it
