[Window] Command group menus do not close after a second window has been closed about aurora HOT 3 CLOSED

This issue still seems to be present on native, decorated windows:

Edit: a second window does not need to have been opened for this issue to be present, unlike the original post.

I think I know why this is happening - in non-undecorated mode the window is using OS-provided title bar. So when you move the window by grabbing that title bar, right now Aurora doesn't get notified in its window-level AWT listener, and the popups like menus, combos etc don't get dismissed.

Ugh, this is not going to be easy to fix.

Over here this is how Swing's popup menu registers itself to get notified on window ungrabbing. Note that it's using internal, undocumented and inaccessible event mask. Then over here it gets notified that the window has been ungrabbed so that it can hide itself. Again, internal and inaccessible event class. And there's also these APIs to grab / ungrab windows to have the whole process rolling.

None of which can be used, especially now that the JDK is heavily restricting access to such internal APIs.
