@rictic The tests seem to be a failure with Firefox; I don't see these locally. Is this an issue with FF in travis, or is this a real problem?

[rictic]

Unsure about the travis errors, check with Dan while I'm out if town. I think last-progress would be a better name for this.

I'd also like to see a test here.

@cdata only fails because of FF error now. Fixed IE issues.

Any progress on this?

Slipped through the cracks during Polymer 2 development

[e111077]

~There seems to be a regression in Polymer 2.0 see: Polymer/polymer#4624~ This is caused by a webcomponents v0 -> v1 spec.

Where is this?

Apparently the tests were wrong. Thanks for the suggestion
