Layered icons break App Structure panel

Just leaving this around for the future.

If you use layered icons in App Connect extensions it will break the AC panel.

You can’t add new components.

Example:

icon: [
        {
          prefix: "fas",
          iconName: "cookie-bite",
          classes: "color-yellow"
        },
        {
          prefix: "fas",
          iconName: "question",
          classes: "color-green",
          transform: {
            size: 8,
            x: 10,
            y: -8
          }
        }
      ]
