[Flask] Unable to set current_user.authenticated to True

The whole problem is that UserMixin.is_authenticated is a bit
counterintuitive as, by default, it always returns True. Contrast that with
AnonymousUserMixin.is_authenticated, which always returns False.
So to check if someone is logged in with login_user, check if
current_user.is_authenticated is True. When no one is logged in,
current_user returns AnonymousUser; if someone is logged in, current_user
returns a User object.
Thus, if current_user is still a User object after calling logout_user,
that’s a bug somewhere. In this case it would be helpful if you could share
a minimum working (well, in this case *not* working) example with us to see
where the problem is.
Best,
Gergely
