      Description

      If a session has a delivery arriving split into multiple transfer frames, and those frames are multiplexed with transfer[s] for other deliveries on the session (i.e there are multiple links on the session), then the transfer frames are mishandled.

      The handling in the transport session is essentially expecting a single outstanding delivery at a time, whereas the spec allows (and proton-j will in certain situations send) multiplexed deliveries for different links on a session. The mishandling can result in a transfer being incorrectly treated as the start of another delivery (potentially leaving earlier bits/ones incomplete) and/or merged with the wrong preceding transfer content.
