Yes, it's fixed in After Effects CC (12.0). It's listed in the bug fixes on this page, as I said above.
No, it's not fixed in the After Effects CS6 (11.0.2) update.
We don't yet know whether it will be fixed in the next After Effects CS6 update. You can cast your vote for it to be fixed in the next CS6 update here: http://www.adobe.com/go/wish
