idp.storage.clientSessionStorageName cookie name

[Cantor, Scott]

That property wasn't meant to be a cookie name, it's the name of the storage key in the browser. It becomes a cookie name if the HTML storage option isn't used, but I never anticpoated that would be a common thing to do (and I wouldn't recommend it).

When I changed the cookie name defaults, I didn't want the storage key to have the prefix, it didn't really make sense, but that means the cookie also didn't change its name if it ends up being used, which creates the conflict because of the path change.
