No badge for outstandingItems in menu for CMS articles

Hello,

if i create a menu link with this setting, i don't see any badge for new created articles in menu :

I think it should be visible, because, if i choose "Forum" and select the forum ID, when there is new threads, we can see the badge with number of new threads or messages..

I don't really know if it's a bug, but i think that should be fixed, to make it work for articles too

Thank you !
