Sensor with device_class enum has always state 'unknown' in trigger-based mode

[rvalitov]

The problem

If I create a sensor with device_class: enum it does not work in trigger-based mode. In this case the options attributes of the sensor are ignored and are not visible in the UI.

Standard sensor (correctly handles the options):

YAML code:

- template:
    - sensor:
        - name: "Garage door status"
          unique_id: garage_door_status
          device_class: enum
          attributes:
            options: "{{ ['This', 'That'] }}"
          state: "This"

Trigger-based sensor seems to ignore the options as a result the state is always 'unknown':

YAML code:

- template:
    - trigger:
        - platform: state
          entity_id: binary_sensor.garage_door_sensor_contact

        - platform: event
          event_type:
            - template_reloaded
            - homeassistant_started

      sensor:
        name: "Garage door status"
        unique_id: garage_door_status
        device_class: enum
        attributes:
          options: "{{ ['This', 'That'] }}"
        state: "This"
