Broken fetch polyfill method in IE11

[bartdominiak]

I'm struggling with the problem on Internet Explorer 11. Does your module support it?

Issue Details:
Fetch polyfill is broken in your core-js lib and it's very hard to fix that, b/c this script is runned on your side in an iframe.

After adding debugger - breadPromise, and breadFetch is undefined.
