@kevinpschaaf if the items are set synchronously, then it works as expected. I believe this is the reason why the smoke test works. Is there anything we forgot to do?

Root-caused to https://github.com/Polymer/polymer/blob/master/src/lib/template/templatizer.html#L385-L389; parent props need to be pulled from the <template> rather than the <iron-list> element.

@blasten Polymer/polymer#2504 is now resolved; can you confirm in iron-list and close? Thanks.
