This fixed the issue of dark mode not displaying on the register, login, forgot password and a few other pages.
This one took me a while to fix, and I still don't really know what is going on here.
The aforementioned pages already implemented a dark mode, but it didn't seem to work for me. After some testing, I discovered that the dark mode preset doesn't load on chromium based browsers.
I have absolutely no idea why that is, if someone could help me with this that would be amazing. I might make an issue out of this later on.
As I still wanted to fix this, I finally achieved my goal by doing the caveman approach:
I first added the usual dark mode detection. The same used on the home and little link pages (see previous commits if you're interested).
Then I wrote and if statement that loads the newly added app-dark.css (see previous commit) that changes text and background color on the pages in question, if the browser type is chromium and dark mode is selected in the browser settings.
"@if(strpos($_SERVER['HTTP_USER_AGENT'], 'Chrome' !== false) and $color_scheme == 'dark')"
This doesn't look optimal, and I would rather just have the same dark mode as on Firefox, but this is the best I can currently do with my available time.
