A drawing over a message whose client_context the answer carries not: the
placement mutation's target_offline_threading_id is that id, a field every
recording of the mutation carries, so without it the request cannot be built.
This is the request's own requirement, not a rule about which messages may be
drawn on — the server decides that. The message's data is the caller's, so the
refusal is a defect before any request is built.
