Okay, so good news is this helped us identify and fix a google apis issue, which is that we managed to point the 3.2.0 version back at 3.1.1, hence the discrepancy with unpkg. We've updated that, so hopefully it will serve the proper version in a day or so.

The bad news is, what you're describing is a three.js regression, so now it will be broken in both places instead of one. I'm hoping it's already been fixed, so we'll get it with our next update to r155. Meanwhile, you'll probably want to pin to 3.1.1.
