IE11: Section navigation issues

[Karthikeya212]

Issue 1: Autoswitch/Autoplay not working in a multi-section item.

Issue 2: Autoswitch/Autoplay not working in a playlist with multiple items.

Issue 3: Cannot navigate to other items in the playlist by clicking on the item. So, cannot play any other item in the playlist except the first.

IE11 is missing support for Array.from (at least). We need to polyfill, or avoid using spread. ( @adamjarling )

Object doesn't support property or method 'from'
plugin_playlist_items.js (24,165)

Hmmm. Interesting. So Babel is being brought into the application through the 'sprockets-es6' gem, or whatever it's named. Can a gem be configured? In this case, like to include a polyfill? Or could we install the polyfill code directly into the application, before our application code is rendered?

As a test, if you chucked this into the app, does it seem to fix whatever is breaking?

Yes. It does solve the problem.

@bkeese @joncameron @davidschober Did this ever get fixed?

[bkeese]

Looks like babel-polyfill is coming in with sme package and also with the timeliner.

We'll need to retest this The package is there, and so it might be fine now.
