[Bug] Worgen Recustomization

I was playing with the recustomization feature (randomly on my account), and I noticed that it seemed like facial hair did NOT work properly. At first, it would just change the Worgen's features, and no change would occur on the human face. Then, perhaps after I scrolled through all the other facial hair options, the human face got a beard, and the scroll buttons didn't change either face any more.

Hitting back and re-entering customization reset the face, but with the same bug as above.
