This state was added by [JDK-6432667](https://bugs.openjdk.org/browse/JDK-6432667): _Vista: Menu dropdown differs while compare with native in vista laf_.

No more background is available… It may be due to how Windows renders icons in menus: if a menu item has an icon, it's rendered at the location where bullets / check-marks are rendered; if you need to display selected / unselected state of such a menu item, you have to use different icons.
