I'm using Azure AD for federated authentication to my multi tenant applicable as per this article:

Its all working well - one minor question I have though is:
When the user tries to access my site and they are automatically forwarded to login.microsoftonline.com the title of the page is 'Sign in to STRID_DISPLAYNAME' which looks a bit broken.
Why is this?
