Changed popup behavior with v5?

[rhegner]

Core Library

MSAL.js (@azure/msal-browser)

Core Library Version

5.2.0

Wrapper Library

MSAL Angular (@azure/msal-angular)

Wrapper Library Version

5.0.4

Public or Confidential Client?

Public

Description

In my code I'm using MsalService.loginPopup().

With @azure/msal-angular 4.0.26, the popup closed automatically after logging in.

With @azure/msal-angular 5.0.4 the popup stays open and shows the redirect page, which is undesirable, at least in my case.

Is this by design? Or is this a bug? (Maybe related somehow internally related to #8316 ?)
