      Description

      Unsure if expected behavior:

      If a receiver settles an inbound message before all frames have arrived, any buffered frames (including frames buffered in the sender) that arrive after the settlement causes the connection to close. See the following router log:

      A reproducer has been added to the router unit tests (early close) via the following patch:
