Are there any news regarding this isssue? This issue blocking the development and testing of our project!

Hey Roman,

Seems that the problem here is that your <link rel="import"> in inside the polymer-element tag. That is currently being compiled incorrectly by our transformers (see issue #18340).

The workaround is simple. Just move the import outside. For example, do:

<link rel>
<polymer-element>

instead of:

<polymer-element>
  <link rel>

Added Duplicate label.
Marked as being merged into #18340.
