Lovelace Entities Card - Title Icon

This is the dumbest thing but I noticed in the lovelace docs the entities card is supposed to support showing an icon to the left of the title. I can’t seem to get this to work. I’ve tried it on several different entities cards, with and without showing the header toggle. No dice. I’m pretty sure my syntax is correct and I know the mdi icon reference is ok as I use it elsewhere. I’m on Hassio 0.100.3. Anybody else actually have this working?

      - type: entities
        title: Household Presence
        icon: mdi:account # THIS DOESN'T WORK
        show_header_toggle: false
          - entity: binary_sensor.google_location_connected
          - entity: binary_sensor.someone_home
          - entity: input_select.occupancy_mode
          - entity: sensor.house_alarm_status

This works since 0.101.x


D’oh. Thank you. Hadn’t gotten around to updating yet.
