Closed requested to merge verdre/gnome-shell:alt-tab-open-close into main
Dynamically add and remove newly opened or closed windows to the different alt tab switchers.
The problems with the
window-created signals are resolved now and the detection should work fine in both Wayland and X sessions with every switcher available.
This MR and !176 (closed) are replacing !92 (closed).
Marked as WIP because this depends on the fix-branches being merged first.
