    workspacesView: Clip the SecondaryMonitorDisplay instead of the view
    
    Make the SecondaryMonitorDisplay a bit more similar to the
    ControlsManager container on the primary monitor, and clip that widget
    instead of the WorkspacesViews on secondary monitors.
    
    This will allow us to overpaint the WorkspacesView allocation and paint
    the WindowPreview overlays like the title and close button outside the
    allocation with the next commit.
