Rotation in mutter is not reported in XRandR with Xwayland
Basically, changing the orientation of an output in GNOME Shell/mutter in Wayland does not update the XRandR and root size correctly anymore.
Downstream issue:

This is a regression introduced by commit da791ed9, but that commit itself was a revert of commit 427f8bc0 which was a revert of commit a0545326… and a bit of commit a0545326 as well for good measure.
So I think we may have an issue between how the different compositors report things, as fixing Xwayland for a compositor seems to break another one.
