Getting a KeyFrameEffect is not defined error

[npezza93]

Seems to be occurring in the opaque-animation component. Only occurs using this gem. Any ideas why this is happening?

*Edit - This might be caused by an issue in polymer-rails gem with the webcomponents.js file

[npezza93]

FIXED When using any neon elements be sure to add the following line to your application.js file:

//= require web-animations-js/web-animations-next-lite.min

Just a quick bump, for anyone wondering.
This was an AWESOME fix thankyou @npezza93

run: bower install web-animations/web-animations-js
and then include in your polymer component:

A bit different to the require but yeah, be aware your folder structure could be different depending where your bower components are.

Thanks again @npezza93
