[Bug 1950040] [NEW] Wayland Screensharing broken in Ubuntu 21.10

[Esokrates]

Public bug reported:

Freshly installed Ubuntu 21.10, screen sharing does not work with any
browser, tested the following options:

- Firefox snap
- Firefox deb
- Chromium snap
- Chromium flatpak

Steps to reproduce:

1. Go to https://www.webrtc-experiment.com/Pluginfree-Screen-Sharing/#7325517390736006
2. Select to share the whole desktop in the xdg-desktop-portal
3. Notice the orange screen share indicator in Gnome-Shell but actually nothing is shared in the browser.

This should be handled high priority since this is a critical feature
during the pandemic.

Filed against ubuntu-meta since I don't know exactly which package to
blame, whether it's pipewire, xdg-desktop portal or some problem
directely with mutter / gnome-shell, please reassign accordingly.
