{code}
The issue is caused by the IGNITE-9492 ticket. The code assumes that the full
message will always be sent by the same node. This is not true, however, in
cause of coordinator failover.
We should check if the message is received from a new coordinator and replace
delayed message (and ignore the ones from the old coordinator).
> Assertion error on full messages merge after coordinator failover
