Authentication Popup not closing for MSAL authentication extension

[cosymon]

Current behavior

When LoginAsync is called using the Authentication service, the popup doesn't send the token back to the main window, but instead sends it to a new page inside the popup.

After looking in the logs I found this error: dbug: Uno.Extensions.Authentication.MSAL.MsalAuthenticationProvider[0] LoginAsync - Error attempting to login [Error - Popup closed]

Expected behavior

The token is sent back to the main window, and the popup closes

How to reproduce it (as minimally and precisely as possible)
