paper-dropdown-menu - overlay not working

[drindal]

Hi!

I've posted a question on Stackoverflow about paper-dropdown-menu. I've managed to get the label part working, by deleting all components and reloading them via bower (master branch of all components).

Now I have the problem, that the dropdown don't show, when clicking on the arrow. The arrow itself is changing (up / down). 

Even the demo.html of the downloaded paper-dropdown-menu doesn't show the paper-items below.

I appreciate any help!

Is your web-animations-js repo at master or a release? It should be at 1.0.1 (declared in core-animation's bower.json). I think the later releases have a bug that causes the issue.

Thanks for your hint! Now it's working again (Problem also mentioned here: https://github.com/Polymer/core-animation/pull/15)

But now i've a kind of double opening of the drop down menu. When I'click on the arrow, the menu opens, closes for 1 sec and then opens again and stays open.

Strange..

That's a bug in the web animations polyfill. Bug here: https://github.com/web-animations/web-animations-next/issues/260
