I don't think anyone has found that it works on X11. On X11, Firefox uses some
custom code to detect the windows that can be shared. It is unclear if the bug
is in the code Firefox uses or in Okular (but
https://bugzilla.mozilla.org/show_bug.cgi?id=1637327#c5 says it also happens
with a QML application, so it may indeed be a Firefox bug).

On wayland, Firefox uses xdg-desktop-portal, and so the windows are correctly
shown.

I can still reproduce it on X11 with:
okular 22.07.80
Operating System: Arch Linux
KDE Plasma Version: 5.25.3
KDE Frameworks Version: 5.96.0
Qt Version: 5.15.5
Kernel Version: 5.18.15-arch1-1 (64-bit)
Graphics Platform: X11
