map_state example from documentation not working

[yesterdayshero]

Trying to use the map_state function based on the example in the documentation and it isn't working.

If I apply the same settings in Home Assistant, I still get the media player title showing in the Banner Card, rather than the values entered in the map_state code.

entity: media_player.office
map_state:
  playing: mdi:disc-player
  not_playing:
    value: mdi:stop
    name: A custom entity heading

I'm hitting the same problem. In my case, I'm using the banner card to show some simple on/off switches (used for sprinklers) this way:

type: custom:banner-card
heading:
  - mdi:sprinkler-variant
  - Garden Irrigation
background: '#EDE7BA'
entities:
  - entity: switch.sprinkler_3
    name: '3'
    map_state:
      'on':
        value: mdi:sprinkler-variant
        name: 'on'
      'off':
        value: mdi:sprinkler-variant
        name: 'off'

In my case, the name field is showing right ("on" when switch is on and "off" when it's off) but icon nevers shows up. I've tried removing the name field (just in case it has priority over the icon or something); icons are still not showing.

I've also tried removing all name fields (the entity one too) and then entity's name is showed.

Any ideas on this?

Thanks!

-- UPDATE --

I had a look at the code and I've seen the following (just a quick look around, maybe this isn't related to this bug):

• renderEntities function uses the renderAsToggle function to render any entity of type light, switch (my case) or input_boolean.
• renderAsToggle function has no code related to the value field and just uses the mwc-switch tag.
• renderValue function seems to be directly related to this issue, but it's only used in renderDomainDefault and renderCustom but not in renderAsToggle.

Maybe this is all intended and the value field is only to be used with custom elements. In that case, would be great to have that info in the docs :)
