[Bug] Rollup issue with web-animations-js eval

[luchillo17]

Importing with Rollup seems to complain about eval sentence:

[14:56:15]  rollup: Use of `eval` (in 
/home/carlos/Carlos/OSGroup/startApp/node_modules/web-animations-js/web-animations.min.js)
is strongly discouraged, as it poses security risks and may cause issues with minification.
See https://github.com/rollup/rollup/wiki/Troubleshooting#avoiding-eval for more details

@Rich-Harris has made some digging and found why this repo plays badly with Rollup, here's his comment: rollup/rollup#1043 (comment)

Any word on whether this polyfill will be updated to be able to be used in strict mode? ES6-ifying it would be cool.

We no longer use eval. Are you still experiencing a problem using web-animations-js with Rollup, or can we close this issue?
