Just looking at this from the webflow end, the reason is that any initial parameters are dropped by webflow by the time the authentication step runs, be it CAS or SAML.

To preserve them, code would have to exist to do so, probably by saving them in the context tree in some custom context. That could be done with some Java code if and only if the CAS login flow is running the inbound intercept hook, I'd have to check on that, or Marvin will know.
