Import stopped working for some modules

Describe the bug

Importing firebase from npm package does no longer work. This seems like a regression as that import worked fine on 0.17.2 for me.

Reproduction

1. npm install -S firebase
2. Add import firebase from 'firebase/app to any JS file.

firebase/app's browser field points to a cjs file... 🤦
