I think we should try and implement this in the initial implementation 
of SwingNode. This is a very annoying bug, and the solution is 
relatively simple - delegate the grab/ungrab requests for the Swing 
"frame" to FX, and send the UNGRAB event from FX back to Swing. This 
should fix 99% problems with popups.
