Adding menu item with ApplicationSpecificRole results in duplicate menu items on Mac OS

For each MainWindow I create a menu bar, a menu, and an item in the menu with an ApplicationSpecificRole.

Qt automatically moves my menu item to the application menu (since it has ApplicationSpecificRole).

Unfortunately, when I have two windows and switch between them, the items in the Application menu are not cleared. This results in multiple copies of my menu item in the Application menu.

This is different behavior from Qt 4.6.

I've attached a sample application. Run the application. It will display two windows. Move the top one and click on the bottom one. Now click in the menu application menu. You'll see two 'Action' items at the top.

Run the same test under Qt 4.6 and you'll only see one.
