Card (new) - Problem with custom theme json

[IP_Kornel]

Hi,

I tried so setup my default setitngs for card (new) visual, I'm able to do most of the things I wanted to setup however I found a problem.

I want to setup default font for referenceLabelValue and referenceLabelDetail like this:

{
  "name": "My New Theme1",
  "visualStyles": {
    "cardVisual": {
      "*": {
        "referenceLabelValue": [
          {
            "$id": "default",
            "show": true,
            "valueFontFamily": "DIN"
          }
        ],
        "referenceLabelDetail": [
          {
            "$id": "default",
            "show": true,
            "detailFontFamily": "DIN"
          }
        ]
      }
    }
  }
}

but for some reason power bi won't read it properly. It loads DIN value for both properties however it sees it as a font that is not "available" and displays it differently and it's not selected (grayed out) on the list as it should be.
Is it because theme is loaded first then power bi loads available fonts for the visual when by default property is disabled? In this case user has to add reference labels and referance labels details before he can change font and since it was done other way around it's like this?

After manual selection

You should clrealy see the difference.

In my opinion it should read that property's value correctly once reference label and details are added.
