There's a workaround (ec18a559c687 ("monitor-manager: Ignore
tablet-mode-switch on initial config of native portrait mode panels")) for
panels that default to portrait mode, where touch mode is disabled, but
a touchscreen is present. This workaround gets applied when we receive
the first reading from the orientation manager.
Make sure this workaround is applied as expected by adding a test for it.
The test needs to be first in the list of orientation tests, because mutter
only applies the workaround on the first orientation event it receives.

Mutter
Mutter is a Wayland display server and X11 window manager and compositor library.
When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.
When used on top of Xorg it acts as a X11 window manager and compositing manager.
It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.
Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork of Clutter, a scene graph and user interface toolkit.
Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.
