Uncaught TypeError: this.isLightDescendant is not a function

This line is throwing it: https://github.com/PolymerElements/iron-behaviors/blob/master/iron-control-state.html#L76

I'm on polymer 1.1.3 right now.

The thing is isLightDescendant is not available until v1.1.5

@notwaldorf Polymer/polymer@1e9110a

but iron-behaviors seems to say polymer ^1.0.0 is ok?

https://github.com/PolymerElements/iron-behaviors/blob/master/bower.json#L19

Looks like this is fixed now (v1.2.0 is the base requirement). If you are stuck on an earlier version of this element, can you include which version is messed up for you in your description and re-open this issue? Thanks!
