Card-modder in vertical-stack-in-card

using the card-modder in a vertical-stack-in-card (I only need to color the background of the top card…)

  - type: custom:vertical-stack-in-card
    cards:
      - type: custom:card-modder
        style:
          background-color: rgba(255, 255, 240, 0.3) #ivory
        card:
          - type: entities
            title: Weeralarm
            show_header_toggle: false
            entities:
              - binary_sensor.meteoalarm_brabant
              - sensor.weer_alarm
      - type: conditional
        conditions:
          - entity: binary_sensor.meteoalarm_brabant
            state: 'on'
        card:
          type: markdown
          content: >
            <font color= grey> [[ binary_sensor.meteoalarm_brabant.attributes.attribution ]] </font>
      - type: conditional
        conditions:
          - entity: binary_sensor.meteoalarm_brabant
            state: 'on'
        card:
          type: markdown
          content: >

            **Alarm code**

            <font color= [[ sensor.weer_alarm.state ]]> -
etc

won’t show the top card in the vertical-stack, which is using the card-modder. All cards below that show fine.

no error in the log afaics.

isn’t this supported?

I can try to use card-modder on the full vertical stack, but that is a hack really, since card-modder only applies to the top card, and that has other side effects I don’t like, especially when using border etc. tried that here Card modder and vertical-stack-in-card but taken that out again, not supported, and not nice.

or should I better use a dedicated theme on the entities card for that? Of course I tried that first before asking, and it does show the full stack. It doesn’t theme the top card though:

  - type: custom:vertical-stack-in-card
    cards:
      - type: entities
        title: Weeralarm
        show_header_toggle: false
        theme: minimal
        entities:
          - binary_sensor.meteoalarm_brabant
          - sensor.weer_alarm
      - type: conditional
        conditions:
          - entity: binary_sensor.meteoalarm_brabant
            state: 'on'
        card:
          type: markdown
          content: >
            <font color= grey> [[ binary_sensor.meteoalarm_brabant.attributes.attribution ]] </font>
      - type: conditional
        conditions:
          - entity: binary_sensor.meteoalarm_brabant
            state: 'on'
        card:
          type: markdown
          content: >

            **Alarm code**
etc

thanks for having a look.
