Segfault with adwaita demo (or phosh-mobile-settings):
$ _build/src/phosh-mobile-settings
(phosh-mobile-settings:11950): GLib-GObject-WARNING **: 18:45:20.837: invalid uninstantiatable type 'GFlags' in cast to 'GtkAccessible'
(phosh-mobile-settings:11950): Gtk-CRITICAL **: 18:45:20.837: gtk_accessible_get_at_context: assertion 'GTK_IS_ACCESSIBLE (self)' failedThis is with a slightly patched libadwaita (https://source.puri.sm/guido.gunther/libadwaita). I can't seem to reproduce with popovers in gtk-4-demo. It isn't reproducible on Debian bullseye with GTK 4.6.
