@scott Right, I believe I’ve fixed it. Could you try again?
Basically, I apply a filter to the body in @media (prefers-colors-scheme: dark) to implement a simple faux dark mode but also apply the filter again to videos, image tags, etc., that should not be inverted. However, when a video goes fullscreen, it’s no longer affected by the filter on the body and so you have to specifically null out the filter for video in the video:fullscreen selector (i.e., video:fullscreen { filter: none; }
