:critical:`[Critical]` Incorrect handling of RTPS messages with submessages from different participants
-------------------------------------------------------------------------------------------------------
When an RTPS message that contained submessages from multiple
participants was received, |me| incorrectly treated each submessage
as though it was from the participant whose GUID prefix was in the RTPS
header. |me| does not send RTPS messages with submessages from
different participants, but other DDS vendors may do this, which would
have led to various communication issues and a lack of interoperability.
