Description

If the sending link calls pn_link_drained() to indicate that it has send all pending data, and afterwards it receives a Flow frame with drain=true from the peer, then the drain never completes.

The ordering is the problem: if the flow frame w/drain=true is received BEFORE the sender calls pn_link_drained(), then it works.
