Pinned tab not visible

[mhdzumair]

Hi @EliverLara thanks for your awesome work. I've been using this theme in my all system for more than a year, I'm not sure if you're still working on this. In the latest Firefox 128.3.0esr for Debian broke the pinned tabs. It is now not visible and not able to click on there.

When I remove the themes and then open Firefox, the pinned tab shows up again. So if I remove the pinned tab and apply the theme and again pin it, then it works fine. However, after the restart again, it's not visible.
