    input-device: Do not unset the device stage after the last touch is lifted
    
    On X11 the pointer will follow a "pointer emulating" touch sequence, so the
    pointer will be effectively left inside the stage after that touch is lifted,
    even though the master device stage is unset. This makes pointer events get
    ignored until the pointer leaves and enters again the stage.
