Successfully tested xdg-desktop-portal 1.14.4-1ubuntu2~22.04.1 from jammy-proposed using the test plan in the bug description, in a clean and up-to-date jammy amd64 VM.
I first reproduced the problem without the update from jammy-proposed, then installed the updated xdg-desktop-portal and reverted to a pristine state by deleting ~/.local/share/flatpak/db/webextensions and ~/snap/firefox, and rebooting the machine. After enabling the chrome-gnome-shell extension, it worked OOTB without the need to restart the portal.
