mysqldump with single-transaction on slave doesn't stop applying binlogs

I have MariaDB replica server for making consistent database dumps, and after the latest update I noticed that mysqldump with --single-transaction option does not stop applying binary logs, e.g. Seconds_Behind_Master not increasing and Exec_Master_Log_Pos counter increasing during dump. I have all data in INNODB tables, and such --single-transaction behaviour looks odd. My mysqldump options are:
--force --quick --single-transaction --routines --triggers

Changing --single-transaction to --lock-all-tables - locking tables, and I see correct blocking database from changes during mysqldump.

Please check current mysqldump with --single-transaction option behaviour.
