Issue Summary

When trying to add a Confluence page as a tab in an MS Team chat the authentication pop-up is served in a loop. The user thinks that they have not logged in and keep trying to auth.

Steps to Reproduce

Pre-reqs 

• Have MS Teams Desktop install
• Install Confluence for Teams via MS Team
• Connect to your Confluence site.
• use SSO auth

1. Open a Teams chat
2. Add a tab and select to add a Confluence page
3. You are prompted to sign in
4. Pop up appears
5. Choose Login with Microsoft, or pick your account from the list
6. Eventually, the pop-up refreshes and shows a login screen again in a loop.

Expected Results

The pop-up directing you to log in should close once authentication is complete.

Actual Results

The pop-up is served over and over but if you close the pop-up, the authentication has actually worked, and the underlying Confluence page refreshes and shows correctly.

Workaround

Close the authentication pop-up screen after logging in the first time
