Describe your problem.

Currently, the gmail theme makes an assumption (requirement?) that a base "dark mode" theme is already selected, which means certain elements will not display properly if the base gmail theme is light. There are specific situations where you cannot apply a dark mode theme to a gmail inbox (such as a delegated inbox, or some enterprise environments) and it would be nice if things worked regardless of the base theme selected. I realize this is annoying as some of the things that do not display properly are images, but I hear tell of dark CSS magic to get them to display properly. Bit of an edge case for sure, but figured I would report as maybe someone a bit more knowledgeable than myself would be able to fix it up quick enough.

Examples below do not cover all instances of this, but if it's helpful, I can try to provide screenshots of things as I come across them. Most are fairly obvious when you have a light mode theme selected. #864 just recently merged fixed a few of these I had noticed and had local patches for, but wanted to raise the larger concern for tracking either way.

Thanks to everyone for all their hard work, and let me know if any additional information is helpful!
