These files aren't loaded client-side, they are only being tested in the jest environment so this allows the babel transpile to complete and the tests to run, tested against the provided failing repo https://github.com/ballpit/dynamic-10.2-bug

We could only allow this if the NODE_ENV is set to test 🤔

This same issue occurs when running [email protected] with the latest storybook so I'm unsure if NODE_ENV will cover all the breaking cases :(

Seems like this problem happens when the babel config resp the next.js preset is used outside of next.js, so it doesn't really matter what the key is.
