xdg-desktop-portal-gnome 44 incompatible with Mutter 43

• xdg-desktop-portal-gnome 44.beta
• xdg-desktop-portal 1.16.0
• Ubuntu 23.04
• mutter 43.2

It appears like deae6336 is incompatible with Mutter/GNOME Shell 43.

In Ubuntu 23.04, we have temporarily reverted this commit until we can finish switching to GNOME Shell 44 Beta. See https://launchpad.net/ubuntu/+source/xdg-desktop-portal-gnome/44~beta-1ubuntu1

I was thinking that LTS distros might be encouraged to backport newer xdg-desktop-portal* release to fully support the latest Flatpak apps. Is that not supported?
