title: Firebase Auth - After updating the user's email, Firebase Auth logs out the user
body: <p>I am using Firebase Auth in my app.  I update the email like follows:</p>
  
  <pre><code>firebaseAuth.currentUser?.updateEmail(email)
  </code></pre>
  
  <p>The email is updating 100% (I do a re-auth when necessary as well).  My problem is after the e-mail has changed, the user is being logged out of his account and has to login again.</p>
  
  <p>When I call</p>
  
  <pre><code>val user = firebaseAuth.currentUser 
  </code></pre>
  
  <p>after updating the email the user is null and my app wants you to login again with the new email address.</p>
  
  <p>Is this the correct behaviour?  It makes for a really bad user experience having to login again after changing the account email.</p>
