To my understanding, this is compatible with the STOMP 1.1 spec that
says that, in case of repeated header entries, "only the first header
entry SHOULD be used as the value". So RabbitMQ just considers "latest"
as the value for dupkey1. When it later sends the MESSAGE frame, only
this value is sent.
