I recently set up a new starter-kit project using polymer-cli 1.7 and I'm attempting to incorporate Google authentication utilizing the google-signin element.
Although the sign in button appears and works for signing in, the signedIn property isn't being properly configured while the expected events (e.g. is-authorized-changed) are not triggering.
The event is-authorized-changed seems to fire twice upon initial page loading but fails to trigger again either when signing in or out.
