Maybe someone one day will have ideas how to fix this.

Should be fixed with #57

@leftos if you have a chance can I re-ask you to take a look into this? It worked in CRC browser, and on local development (in Firefox), but it does not work in Firefox on prod.

Alright @leftos @dreamnid, after more investigation, it seems like when your BROWSER is in a dark theme, using this code inverts the (already dark) PDF background color. So if your browser is in a dark theme, only the PDF should get inverted. If your browser is in a light theme, auto dark mode/dark mode should function as written now.

But I can't figure out how to fix it...

ChatGPT concludes this is not possible to change...

#65 fix this in Firefox, but still broken on Chromium browsers.
