Steps to reproduce the problem:
1. Click on the user icon at the top right.
2. Type username and password while having 2-factor auth enabled with the Google Auth app.
3. Click on "Try another way to sign in".
4. That closes the popup, then opens a new tab in Google Chrome where the login process has to be restarted from the beginning.
5. Enter username/password again
6. Click on "Try another way to sign in" again.
7. After successfully signing in, nothing happens.
8. Try the process again from the top right user icon, and the whole thing starts over again, and never logs in.

What is the expected behavior?
I should get logged into Chrome to sync bookmarks, settings, etc.

What went wrong?
It doesn't work.
