Nevermind! This is unrelated.

@JamesIves Do you know what ended up being the cause of this? I'm running into the same issue and it seems like it is related to react-hot-loader 🤔

Can't upgrade from 4.12.3 for this reason

Just see this. I actually ran into the very same problem. it seems the code run before polyfill is loaded, which cause an error on ie 11. I have opened a PR https://github.com/gaearon/react-hot-loader/issues/1304 to fix it.
