Custom Scrollbar Styling Conflicts with Dark Reader – UBG98 Workaround Feedback?

Hi Mozilla Community,

I’m working on a CSS customization tool called UBG98 that allows users to inject custom scrollbar styles via a browser extension. However, I’ve noticed conflicts with Dark Reader’s default dark mode styling, particularly on sites like GitHub and Reddit. The scrollbar theming overrides from both extensions clash, causing visual glitches.

Here’s a snippet of the CSS I’m using for scrollbars:

::-webkit-scrollbar { width: 10px; }
::-webkit-scrollbar-thumb { background: #UBG98-brand-color; }
