Test failed with:

TASK [service-check-containers : mariadb | Notify handlers to restart containers] ***

ERROR! The requested handler 'Restart mariadb container' was not found in either the main handlers list nor in the listening handlers list

Looks like this was fixed as part of a different patch, I've extracted that out here
