Log Filter Not Working

While the global log level is warning I want to suppress warnings about automations “Already running”:

2023-11-18 17:23:50.106 WARNING (MainThread) [homeassistant.components.automation.garage_lights_mutual_control] Garage Lights - Mutual Control: Already running

I set this log filter yet the messages keep showing up:

logger:
  default: warning
  filters:
    homeassistant.components.automation:
      - ".*Already running.*"

The regex matches any line containing “Already running”, which will be filtered out. I guess then the problem is the component namespace. Shouldn’t homeassistant.components.automation apply to all automations?
