    [x11] Fix coordinate space of rect in gdk_x11_surface_get_frame_extents when called on popups.
    
    If we take the early return we don't unscale this at the bottom of the
    function, causing wrong coordinates in HiDPI screens.
    
    This bug also affects GTK3 (I noticed this running Firefox tests on X).
