[Bug]: Firefox window preview doesn't appear in the overview

[Milli189]

What happened?

Firefox as of now is the only app that I've seen not having a preview when opening the overview, Brave for example has the preview, but with firefox only the name appears in the overview and the window preview is just transparent

I've compiled the Singularity desktop on Fedora 44 Gnome

Steps to reproduce

1. Open Firefox
2. Open the preview.

Expected behavior

Firefox has a window preview in the overview.

Had to re-open because the fix was working but introduced a critical regression causing the shell to loop crash. I am investigating.
