Some of the modal tests fail in X11 compatibility mode on Wayland, because a mouse click emulated with XTEST does not not cause the windows to be reordered.
This is a known limitation because these click events do not leave the XWayland server and are not reported to the Wayland compositor. There is a [libei](https://gitlab.freedesktop.org/libinput/libei) that can be used to emulate input events in Wayland. And there is a [bridge that allows emulated events from XTEST to be passed to the compositor](https://gitlab.freedesktop.org/libinput/libei/-/blob/main/README.md?ref_type=heads#xwayland-and-xtest). Support for this has been added in [Gnome 45 and XWayland 23.2](https://gitlab.gnome.org/GNOME/mutter/-/issues/3194#note_1937109), but it is optional and not yet enabled in Ubuntu. This change adds `toFront` calls for mouse clicks that are only intended to bring a window to the front in the window stacking order. The testing is green on all platforms. ------------- Commit messages: - 8280990: [XWayland] XTest emulated mouse click does not bring window to front.
