Seems like an isolation issue. core-js is a polyfill for a variety of standard methods, like array.concat(), apparently. It's supposed to support older browser that had not implemented new features.

I think it is related to Babel, its plugin @babel/preset-env adds this polyfill (where needed). Maybe the compiler should add this as a peer dependency? Not sure why this is failing for this component and not for others.

@JoshK2 - do you have any insight about this?

@Tallyb , If I remember correctly, you're working on a new Jest compiler. If so, please keep this issue in mind.
