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 use PaperWM extension for GNOME, it does auto-tiling unusual and simple way (but it has very powerful overrides). All apps appear on apps layer, they appear each after one, and any app could be put on scratch level (switch layers or perma-override), scratched apps are always above other apps or on top.
