When the user pops up a JComboBox (hits the
spacebar for Metal L&F), and then tries to
navigate with the arrow keys, any ActionListeners
for that CB will have their actionPerformed
methods called, and there isn't any information in
the given ActionEvent to show that this was only a
navigation action rather than a selection
(spacebar) action.
