Bug description

There is a reported bug about the dark theme and invisible text, but the user reports it's a caching problem. This is not a caching issue, as it happens even after clearing my cache and using a new computer with a fresh browser.

There are two trouble spots:

1. When in mobile, the three dots to navigate to other apps (Notes, Files, Phone, Music, etc) the dots are black while the other icons are all white. This makes the dots completely hidden.
2. When in Nextcloud office, specifically the excel sheet, the text in the cells are black. When editing the text, in the header, the text is white, but in the grid itself, it is black. Making it impossible to see.

I really enjoy the dark theme, but with these two issues I especially have to revert back to the light theme. Please fix.

Thank you.

Steps to reproduce

1. Enable Dark Theme
2. Go into mobile to view the dots
3. Go into Nextcloud office (Excel) to view the cell font color.

Expected behavior

Font should be white, not black.
