title: Firebase/auth import source-map warnings
body: <p>I am building a react app with firebase library v7.15.5 and when I'm importing 'firebase/auth', it works fine but it throws me warnings in a terminal:</p>

  <p>This is the code of the file, where I initialize firebase modules:</p>
  <pre><code>import app from 'firebase/app';
  import 'firebase/database';
  import 'firebase/auth';
  
  const config = {
    apiKey: process.env.API_KEY,
    authDomain: process.env.AUTH_DOMAIN,
    databaseURL: process.env.DB_URL,
    storageBucket: process.env.STORAGE_BUCKET,
  };
  
  app.initializeApp(config);
  
  const database = app.database();
  const auth = app.auth();
  
  export { database, auth };
  </code></pre>
  <p>Tried to remove node_modules and reinstall all, but it doesn't solve the problem. Maybe I should import it in a different way or configure webpack or tsconfig? I don't know.</p>
  <p>Thanks for help.</p>
