Firebase Auth Web choosing incorrect Google OAuth Client ID

[Jacob]

I'm developing Firebase Auth integration into my app using the Web SDK. I'm configuring a development Firebase project when calling firebase.initializeApp, but for some reason signInWithRedirect to Google is choosing a production project OAuth Client ID, instead of the development project OAuth Client ID. In the Firebase Console, the Google sign in settings has the correct Web client ID under Web SDK Configuration. So why is Firebase choosing a different client ID? How do I fix that?

Thanks.
