I am using fedora silverblue and in the native version of Firefox, the picture in picture window does not have always on top enabled. Is there anyway to change a setting such that always on top is enabled by default. I know it is supported on gnome+fedora because the flatpak version(I downloaded to test this behaviour) has this enabled by default.
I usually right click the window in the app bar and choose the “stay on top” option. This issue only happens in Wayland, also. in X11 it stays on top as expected.
