MQTT message to virtual topic subscriber queue with QOS 2 and retain=true converted to non-persistent message

If a client publishes a message with QOS=2 and retain=true to VirtualTopic.A, the subscriber queue Consumer.A.VirtualTopic.A receives a NON-PERSISTENT message. If the retain flag is set to false, the subscriber queue Consumer.A.VirtualTopic.A receives a PERSISTENT message.
