Automatic dark mode (in CSS) was implemented in #1069, then broken in #1641 because it moved the no-js class to a different element. This PR restores the functionality. It also implements #2134 properly.
I also noticed that the original implementation depends on the light class to be set, which it is not if a different default theme has been chosen. I have also fixed this.
