[Designer] ProgressBar can not bind `value` and `max` to data

Problem Description

I want to use ProgressBar to show progress where I know the range and a current state, but I can not bind data to it it seems.

Card JSON

{
    "type": "AdaptiveCard",
    "$schema": "https://adaptivecards.io/schemas/adaptive-card.json",
    "version": "1.6",
    "body": [
        {
            "type": "TextBlock",
            "text": "Copilot Monthly Quote",
            "wrap": true
        },
        {
            "type": "ColumnSet",
            "columns": [
                {
                    "type": "Column",
                    "width": "stretch",
                    "items": [
                        {
                            "type": "ProgressBar",
                            "value": "${value}",
                            "max": "${max}"

                        }
                    ],
                    "backgroundImage": {
                        "verticalAlignment": "Center"
                    },
                    "style": "default",
                    "showBorder": true
                },
                {
                    "type": "Column",
                    "width": "auto",
                    "items": [
                        {
                            "type": "TextBlock",
                            "text": "25%",
                            "wrap": true
                        }
                    ],
                    "backgroundImage": {
                        "verticalAlignment": "Center",
                        "horizontalAlignment": "Center"
                    }
                }
            ]
        }
    ]
}

Start by reproducing the provided Card JSON in the Designer and inspect how ProgressBar handles data binding for value and max. Done means both properties resolve from card data and the rendered progress reflects those values.
