<Swing Dev> [10] RFR JDK-8173739: JPopupMenu does not disappear on KeyEvent

[Prasanta Sadhukhan]

OK. Updated webrev to post ungrab from a method when internal frame is 
deselected.

There is no grab event. When popup menu is visible, it grab window in 
BasicPopupMenuUI
public void stateChanged(ChangeEvent e) {
             MenuSelectionManager msm = 
MenuSelectionManager.defaultManager();
             MenuElement[] p = msm.getSelectedPath();

             if (lastPathSelected.length == 0 && p.length != 0) {
                 grabWindow(p);
             }
