Card-modding a conditional card

So I thought I’d give card-modder a try to style a conditional card used for weather alerts when one is issued.
For my conditional card I have the state_not: ‘unknown’ set so for testing I change this to state: ‘unknown’
I figured out the styling, got it all set and changed back to state_not: ‘unknown’ but the card will not hide if the styling is in place.

Here is the card in it’s natural state:

  • type: conditional
    conditions:
    • entity: sensor.ec_warning
      state_not: ‘unknown’
      card:
      type: entities
      entities:

and here it is with the card-modding in place:

  - type: conditional
    conditions:
      - entity: sensor.ec_warning
        state_not: 'unknown'
    type: custom:card-modder
    style:
      background-color: rgba(251,13,13,1)
      border-radius: 5px
      --primary-color: white
      --paper-item-icon-color: white
    card:
      type: entities
      entities:
        - type: weblink
          name: Weather Alert
          icon: mdi:weather-lightning-rainy
          url: https://weather.gc.ca/warnings/report_e.html

No styling and everything works perfectly.
With styling it looks good but doesn’t hide.

Formatting will get you every time

  - type: conditional
    conditions:
      - entity: binary_sensor.bad_weather
        state: 'on'
    card:
    type: custom:card-modder
      style:
        background-color: rgba(251,13,13,1)
        border-radius: 5px
        --primary-color: white
        --paper-item-icon-color: white
      card:
        type: entities
        entities:
          - type: weblink
            name: Weather Alert
            icon: mdi:weather-lightning-rainy
