> all dropdown/combobox lists in MP3tag in Dark mode started showing a white solid rectangle when hovering with the mouse or navigating with the keyboard Up/Down arrows. The proper dark-mode selection highlight is completely missing.

This should be fixed with [Mp3tag v3.37-beta.3](https://community.mp3tag.de/t/455). Please let me know if this fixes the issue for you.
