This test can be used to verify that the not-allowed cursor is shown during an invalid drag-and-drop operation. 
        In particular, if the effectAllowed is  and the dropEffect of the 
        drop target is  then the drop is not allowed and the cursor should
        change to the not-allowed cursor. Note, this test only pertains to the Windows build since the Mac build does not show a drop cursor
        for a not-allowed drop operation (see bug #25925).
        
        Drag the red square over the drop target (demarcated by the dashed boundary). While hovering over the drop target, if the cursor

Items that can be dragged to the drop target:
