Universal Media Player Component Missing Pause Button

Configuration
1

I’m using a universal media player component to allow audio and source control through a Logitech Harmony Hub on a Chromecast. I finally got it working correctly, but for some reason the pause and progress buttons are missing. Is this expected behavior?

platform: universal
name: Living-Room-Watch-Chromecast
state_template: >
  {% if (states.remote.living_room.attributes.current_activity == "Chromecast") %}
  on
  {% else %}
  {{ states('media_player.living_room_chromecast') }}
  {% endif %}

children:
  - media_player.living_room_chromecast
  - media_player.samsung_tv_remote

commands:
  turn_on:
    service: remote.turn_on
    data:
      entity_id: remote.living_room
      activity: 'Chromecast'
  turn_off:
    service: remote.turn_off
    data:
      entity_id: remote.living_room
      activity: 'PowerOff'
  volume_up:
    service: remote.send_command
    data:
      command: VolumeUp
      device: 45280036
      entity_id: remote.living_room
  volume_down:
    service: remote.send_command
    data:
      command: VolumeDown
      device: 45280036
      entity_id: remote.living_room
  volume_mute:
    service: remote.send_command
    data:
      command: Mute
      device: 45280036
      entity_id: remote.living_room

Nevermind, I had the template set wrong. This works:

state_template: >
  {% if (states.remote.living_room.attributes.current_activity == "Chromecast") %}
  {{ states('media_player.living_room_chromecast') }}
  {% else %}
  off
  {% endif %}
