The issue looks like an upstream one, could you report it as well on https://gitlab.gnome.org/GNOME/gnome-shell/issues/ ? The fact that the screen is forced back to its non-rotated mode when connecting the other display seems like it could be the same bug (shell refuses to handle rotations when an external screen is connected)
