Bug Description

Impact
------
xdg-desktop-portal 1.14.3 has a single change fixing a consistent crash when using the experimental Wayland feature in TeamViewer.

Original Bug Report
-------------------
Crash happened a short time after starting a screen cast / remote desktop session using the Freedesktop portal API in a Wayland session with mouse and keyboard input. Screen cast continues to run (i.e., PipeWire stream), but input stops.

Can be reproduced by using the experimental Wayland support of TeamViewer (https://community.teamviewer.com/English/discussion/122410/teamviewer-support-on-wayland-experimental-state-%F0%9F%A7%AA)

Reported upstream as well: https://github.com/flatpak/xdg-desktop-portal/issues/771

I can confirm that this is fixed with 1.14.3-0ubuntu2 - I could not reproduce the issue anymore after updating to that version. Thanks a lot for you effort!
