When replicated events are from Master unaware of MariaDB GTID their handling by the Parallel slave misses Seconds_Behind_Master updating. In the bug condition the Show-Slave-Status' field remains unchanged. Because in such case event execution is sequential the bug is fixed with deploying the same logics as in the explicit single-threaded mode with is to set Relay_log_event::last_master_timestamp member early at the end of event reading from the relay log.
