Believe me I've been following this issue closely for a long time and know the status. While the large work that was needed has been done, it hasn't been fixed completely. In my case I get evaled items to show up but they 1) don't have actual names just foo.js -> eval and 2) don't have the actual source shown. I think this might be the issue that is blocking me: https://bugzilla.mozilla.org/show_bug.cgi?id=833744
So while this is "on the road" to being fixed, it's not fixed completely.
