[wayland] Apps button disappeared after switching from portrait to landscape mode

[Alexander Kallenbach]

As described above. I first rotated my laptop to work with it in portrait mode. When I switched back to landscape mode, the Gnome Shell button was gone. If I switch back to portrait mode the button is visible again.
I will attach a screenshot to better explain what I mean.

This bug does not occur in an X session.

Does it happen every time you do those steps? Could you add your journalctl log around the time of the issue?

[Alexander Kallenbach (kallenbachalex)]

Tried again to do so. The bug didn't appear this time.
