On the refresh session and end session endpoints, in 3.2.1 and 3.2.3, cookies are not mentioned.

While the spec give the impression that these calls will be performed front-channel, I'm not sure if it is explicitly mentioned. Implementors might (with good reasons) try at least two alternatives:
1. Do a completely backchannel call,
2. Do the requests in a hidden iframes.

The first, will cause a problem if the provider expects cookies to be present; which is likely to happen as there is no session indentifier in the id_token.
The second may cause problems with cookies in some rare browser settings.

Both will cause problems when the provider decides to involve user interaction; as part of  in.e. the logout flow.

May be it would be a good idea to add a 'display' parameter to these endpoints.
