Rookie question (likely!) or problem with 0.88.1 (unlikely!)

Configuration

I have a simple automation which turns on a light when it is dark. Whether it is dark or not is determined by a binary sensor which I can assure you is off now.

Why then does the light go on at every HA restart?

  - alias: Hall light on when dark
    initial_state: on
    trigger:
      - platform: state
        entity_id: binary_sensor.dark_hall
        to: 'on'

      - platform: homeassistant
        event: start

    condition:
      # Check it is dark (for when triggered by HA restart)
      - condition: state
        entity_id: binary_sensor.dark_hall
        state: 'on'

      # Check it is after 8am
      - condition: time
        after: '08:00:00'

    action:
      - service: homeassistant.turn_on
        entity_id: switch.hall_light

Because you have a second trigger for that automation when HA is started

Yes but the first condition should fail.

      - condition: state
        entity_id: binary_sensor.dark_hall
        state: 'on'

If anyone comes here later, look here for the (probable) answer.
It looks like it is to do with timing and slightly more complex than it appears.

And apologies for the apparent duplicate question but there was an outside chance it was something brought in by 0.88.0 and ‘The Great Migration’.
