Switcher crashes when opened twice over an open "hide on lose focus" guake window on Wayland

[brettk-git]

The following steps lead to a complete crash and logout of Gnome (steps tested on a fresh Fedora 39 installation):

1. log in using Wayland (not Xorg);
2. install and enable the Switcher extension;
3. open a terminal, run "guake -p";
4. in the "Main window" tab, check the "Hide on lose focus" option, close the preferences window;
5. in another terminal, type "guake-toggle" to make the guake window appear;
6. now the guake window has appeared, press Super+W to make the Switcher window appear;
7. at this point the guake window has disappeared by itself, which is normal; press Esc to make the Switcher window disappear as well;
8. repeat steps 5) and 6); now the crash occurs.

Would you have something in the logs? I'm wondering where the bug in that even is, guake, switcher, or gnome shell

[brettk-git]

I would think the bug may come from switcher, or from gnome-shell, or from both (I doubt it comes from guake).
My logs show this
