      Description

      FULL PRODUCT VERSION :
      ubuntu 16.04

      A DESCRIPTION OF THE PROBLEM :
      I am seeing an issue when using setComponentPopupMenu.

      When you use setComponentPopupMenu in a window and create a modeless dialog and position that over that window, then when mouse is dragged with the left button pressed, to the modeless dialog from the parent window, and then the right button is immediately pressed,
      then the popup is fleetingly shown.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      - Run the test program
      - Want until the modeless dialog is shown on top of the main frame.
      - Make sure the main frame has the focus
      - Drag mouse with left button pressed and when the mouse is in modeless dialog, immediately press right button.
      - The JPopupMenu that was installed on the main frame's root pane is shown fleetingly.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The JPopupMenu that was installed on the main frame's root pane should not be shown
      ACTUAL -
      The JPopupMenu that was installed on the main frame's root pane is shown

      REPRODUCIBILITY :
      This bug can be reproduced always.
