test_overrides_gtk.py::test_menu_popup crashes because of a Gdk warning

When I try to run tests locally:

tests/test_overrides_gtk.py .Gdk-Message: 19:57:21.930: Window 0x5555562fe1a0 is a temporary window without parent, application will not be able to position it on screen.

(moo:755748): Gdk-WARNING **: 19:57:21.930: Couldn't map as window 0x5555562fe1a0 as popup because it doesn't have a parent

• PyGObject - git master
• gobject-introspection - 1.68.0
• glib - 2.68.3
• gtk3 - 3.24.30
• Arch Linux, Gnome Shell on Wayland (if it matters).

Tried running tests under xvfb-run - same issue.
