Illegal Constructor for neon-animations and tooltip

[JableSoHo]

Im using ES6 with polymer and am using the master branch which includes the latest code to support ES6 - #2329. Have been getting this :

error TypeError: Illegal constructor
    at TypeError (native)
    at paper-tooltip.Polymer.NeonAnimationRunnerBehaviorImpl._configureAnimationEffects (http://polygit.org/polymer+:master/components/neon-animation/neon-animation-runner-behavior.html:44:53)

Here is a jsbin illustrating the problem:

I saw your jsbin, but there are not any error. so where do you use paper-tooltip in?

@laco0416 Sorry, I have added the tooltip

I believe this is due to the fact that we are now calling registered before Polymer performs registration tasks. It's not specific to using ES6 per se, but rather neon-animation-behavior and therefore paper-tooltip are not functioning correctly. The issue is at https://github.com/PolymerElements/neon-animation/blob/master/neon-animation-behavior.html#L41.

These changes were not intended to be breaking, but we also anticipate registered to be fairly rarely used at the moment so we'll need to consider if Polymer or neon-animation should be changed.
