In the error log, in can be seen this is due to the SQL thread trying to stop while having non-transactional changes:
2024-03-18 15:28:45 71 [Warning] Slave SQL: Request to stop slave SQL Thread received while applying a group that has non-transactional changes; waiting for completion of the group ... , Gtid 0-1-4, Internal MariaDB error code: 0

2024-03-18 15:28:47 71 [ERROR] Slave SQL: Fatal error: ... Slave SQL Thread stopped with incomplete event group having non-transactional changes. If the group consists solely of row-based events, you can try to restart the slave with --slave-exec-mode=IDEMPOTENT, which ignores duplicate key, key not found, and similar errors (see documentation for details). Gtid 0-1-4, Internal MariaDB error code: 1593

The test itself doesn't have any transactions directly, but it can be seen that this is from trying to replicate test suppressions:
The result from queries just before the failure was:
