AADB2C Support Redirect Endpoint with Query String
When registering an application endpoint in Azure B2C if the endpoint requires a query string parameter it won't accept it, e.g. the implicit flow endpoint of Azure API management ends with ?authServerId=GUID; add support for endpoints with query strings.

Most (all?) Word Press OAuth plug-ins seem to require a query string in the reply URL. The OAuth 2.0 spec indicates that query strings should be allowed in a reply URL. Please fix this!
The OAuth 2.0 spec (RFC 6749) Section 3.1.2, in reference to the redirection endpoint:
“The redirection endpoint URI MUST be an absolute URI as defined by [RFC3986] Section 4.3. The endpoint URI MAY include an “application/x-www-form-urlencoded” formatted (per Appendix B) query component ([RFC3986] Section 3.4), which MUST be retained when adding additional query parameters. The endpoint URI MUST NOT include a fragment component."
