Deprecation of HTML Imports styling the main document

[ghost]

I've updated Polymer and all elements this morning, and I still get the message in console :

[Deprecation] Styling master document from stylesheets defined in HTML Imports is deprecated, and is planned to be removed in M65, around March 2018. Please refer to https://goo.gl/EGXzpw for possible migration paths.

Warning disapear if I remove from my index.html any paper-* element included with

<link rel="import" href="bower_components/paper-*/paper-*">

What can I do to remove the warning in console ?

Thanks a lot

Thanks for the information, didn't see this issue
I'm just going to cross my fingers, hoping that everything will be fine.

thanks a lot

@bastienarm don't worry, the Polymer team has already implemented the fix mentioned above so the upcoming change won't break anything. See also this blog post for detailed explanation
