Pipewire window capture freezes after switching to tablet mode.

Hi,

I have a problem with WebRTC screen sharing. When I do the following:
1. Open Google Meet
2. Share my window through the browser. The share works as expected.
3. Switch to tablet mode (i.e. use the 360 hinge to convert the 2-in-1 laptop into tablet)

The shared window freezes and doesn't update. If I share the window after I've switched into the tablet mode or share the whole screen, not just a single window, then everything works.
The same issue happens with any other browser or if I try to use the PipeWire Window Capture through OBS Studio, that is, this is related to pipewire and not webrtc/browser.

Journal says nothing, the only thing that happens when switching to tablet mode and back is:

Do you have any ideas how to debug it?

My setup:
- KDE Plasma + Wayland + wireplumber.
- Dell Latitude 7440 2-in-1
(I also reported it in the pipewire issue tracker)
