I think in UrlService you should compare redirectUrl and  currentUrl without QueryParams AND fragment

Hello!
I think I have the same issue when I try to use implicit Flow , there is a fragment #access_token in the redirectUrl, so when the service compare urls without queryParams, the fragment is not removed , and the urls don't match.
So I agree, we should compare redirectUrl and currentUrl without QueryParams AND fragment
