Run application as root cause application icon in top panel to does not have app menu
thats a consequence of how the app menu is implemented. binaries that are running as another user don't have access to your session bus. Thus, they don't have an app menu and are not fully integrated in the session in various other ways.
As Matthias said, plus WONTFIX, because we can't really.
