Context menu and submenu disappears after a right click

[nicwe]

If you use a application menu with submenus and do a right click on a submenu item, both, the context menu and the submenu will be closed after a short moment.

Steps to reproduce:

• Start the showcase application
• Switch to the application menu (not backstage)
• Open the application menu (Click on "File")
• Right click on "Text document" in the submenu of "New"
• Both, the context menu and the submenu will be closed after a short moment

That's a bug we inherit from MenuItem from WPF itself.
Will try to create a workaround for this issue.
