Custom custom:canary-card doesn't work as expected

[cadavre]

The problem

If canary is not loaded into browser resources yet – styles are not applied. Fresh loads, without cached assets, always causes style not being applied to the card. This is expected. Another refresh (without cache clearing) makes cards looks good, with styles applied. (Look more details below.)

To solve this issue I guess that custom:canary-card was introduced. Unfortunately this card doesn't work as expected, producing:

I get the exact same issue you are seeing.

type: custom:canary-card
card:
  type: vertical-stack
  in_card: true
  cards:
    - show_current: true
      show_forecast: false
      type: weather-forecast
      entity: weather.tomorrow_io_the_browns_daily
      no_card: true
    - type: entities
      entities:
        - type: section
          label: Weekly Forecast
      show_header_toggle: false
    - show_current: false
      show_forecast: true
      type: weather-forecast
      entity: weather.tomorrow_io_the_browns_daily
    - type: entities
      entities:
        - type: section
          label: Hourly Forecast
      show_header_toggle: false
    - show_current: false
      show_forecast: true
      type: weather-forecast
      entity: weather.tomorrow_io_the_browns_hourly

If I edit the card in the dashboard by adding and removing a space ( not making any actual changes just need the save button to work) the error goes away, until the next time I open home assistant, then it's broken again.
