onShowing and onShown InternalWindowEvent handlers are not working

[RaviOnline]

Hi,

The WINDOW_SHOWING and WINDOW_SHOWN event handlers aren't getting called.

I used the following simple code for testing:

window.setOnShowing(e -> System.out.println(e.getEventType()));
window.setOnShown(e -> System.out.println(e.getEventType()));

desktopPane.addInternalWindow(window);

I also attached the following InternalWindowEvent handlers and they all worked fine.

window.setOnMaximizing(e -> System.out.println(e.getEventType()));
window.setOnMaximized(e -> System.out.println(e.getEventType()));

window.setOnRestoring(e -> System.out.println(e.getEventType()));
window.setOnRestored(e -> System.out.println(e.getEventType()));

window.setOnMinimizing(e -> System.out.println(e.getEventType()));
window.setOnMinimized(e -> System.out.println(e.getEventType()));

window.setOnHiding(e -> System.out.println(e.getEventType()));
window.setOnHidden(e -> System.out.println(e.getEventType()));

window.setOnCloseRequest(e -> System.out.println(e.getEventType()));

Please let me know if you need any additional info. I'm using the latest 0.12.0 release.

Regards,
Ravi
