Forum names visibile when forum is private and no public messages

I could have sworn (maybe it was an earlier release) that Forum names which are set to private are not supposed to appear at all to visitors (non-members) of a OG listed in the directory?

So, if I have a public OG, and I set General Discussion to private it shows in the forum/nid page for that group. If I create Private Discussion and don't set it public also visible. Messages posted internally are, of course, public or private by virtue of OG itself.
