[0.9.2] dom-repeat issues in 0.9.2

[jeffposnick]

Somewhere between 0.9.0 and 0.9.2, it seems like a bug's been introduced in <dom-repeat>. Here are two JSBins illustrating the problem, nested inside of a <dom-bind> parent:

Working 0.9.0: http://jsbin.com/topize/3/edit
Broken 0.9.2: http://jsbin.com/fuxode/2/edit

In 0.9.2, the <template> content isn't being stamped out to the DOM. By the time the WebComponentsReady is fired, the property on the parent <dom-bind> that is being repeated is set to undefined.
