Thanks @hkosova!

Based on your report, this appears to be limited to us incorrectly rendering an empty ModelExample -- that is, we aren't ever not displaying valid data. As such, I think a hot fix isn't necessary, we can fix this in the next couple of weeks and ship it out on a Friday.

Let me know if I've missed something, or you disagree!
