I follow the example of signing in with Google, and I noticed that adding the line import { auth } from 'firebase'; adds extra 400kb to my application size. This seems a lot just for the auth.GoogleAuthProvider. Is this a bug with tree shaking? Can I import auth.GoogleAuthProvider from somewhere else? Is there a better way to import GoogleAuthProvider?

Note that this is the only place in my application where I'm importing something directly from 'firebase'
