Device class not honored

[TheRealLouCipher]

Using a binary_sensor as entity with device class door show on and off in card instead of open closed.

See my sample:

  - entity: binary_sensor.deursensor01
    name: Meterkast
    map_state:
      'on': 'mdi:door-open'
      'off': 'mdi:door-closed'

Thank you for sharing the solution to this! I thought I was going crazy. Here's what I did:

map_state:
      'on': Open
      'off': Closed
