XFCE sets GNOME mouse cursor size to 0 (breaking Gnome on Wayland)

Apologies if I'm reporting this to the wrong sub-project, but I'm not sure whether it's the settings or the session that triggered the problem.

I installed XFCE on my Fedora 42 system yesterday (using the distro RPM packages) as an alternate desktop, figuring it was a good candidate for keeping an X11 session around after Gnome removes theirs. I logged in, ran a couple of programs to make sure it was working, then logged out and tried to log into my existing Gnome/Wayland session, Gnome crashed, and GDM locked up. I eventually located a forum post by someone on Arch who had exactly the same thing happen, and traced it to org.gnome.desktop.interface cursor-size having been set to 0 after running XFCE the first time. Manually resetting it solved the problem.

Obviously the crash itself is a bug in Gnome, and it's been reported there. But It seems weird that XFCE (or something related) is setting the GNOME cursor size to zero.
