The timing of this bug report would be right for this being a regression
when used with GTK 4.17.x (which was uploaded to unstable 4 days ago
and migrated to testing today). However, I thought the upstream 47.2
release had already fixed compatibility with GTK 4.17.x...

Perhaps that only worked in native Wayland mode? Are you running GNOME in
X11 mode ("GNOME on Xorg")?

This is the equivalent of
https://github.com/flatpak/xdg-desktop-portal-gtk/commit/fe253f0a3296d44e23c6075b1d78638da78abe71
(but without the backward-compatibility).
