    constraints: Use ConstraintInfo window size when placing
    
    The frame rect will at this point not be set for Wayland popups, since
    the popup is placed and constrained before the actual buffer will be
    attached. To still be able to calculate a proper monitor to be used for
    constraining, use the ConstraintInfo::current dimensions instead, since
    they will have the expected size. This should not cause any issues with
    present paths since when a window is otherwise placed, it usually
    doesn't change monitor calculation result.
    
    This fixes opening a popup menu that would be positioned on the left
    edge of a not-left-most monitor, for example a 'File' menu on a window
    maximized on a second monitor.
