If an application using libmosquitto gets a message which has been delivered with QoS 2, then all properties are not delivered to the callback method which has been registered with mosquitto_publish_v5_callback_set().
The reason for that lies in file handle_publish.c, line 159: In case of QoS 2 messages, the message is not delivered right away, but put into a delivery queue with the method message__queue. Since this queue doesn't seem to support properties, they got dropped at this place and can no longer delivered to the application code.
