Image set to stretch size on adaptive cards doesn't work in Teams when expand images is set to true

[danielmacedo90]

Following the docs and using "msteams": { "allowExpand": true } for my images in adaptive cards, images set to stretch are not resized.

Sample JSON:

{
  "type": "AdaptiveCard",
  "version": "1.2",
  "body": [
    {
      "type": "TextBlock",
      "size": "extraLarge",
      "weight": "bolder",
      "text": "Test Full Width (Expand Image)",
      "wrap": true
    },
    {
      "type": "Image",
      "size": "stretch",
      "url": "[URL_IMAGE]",
      "altText": "",
      "msteams": {
        "AllowExpand": true
      }
    },
    {
      "type": "TextBlock",
      "text": "Test Full Width (Expand Image)",
      "wrap": true
    }
  ],
  "msteams": {
    "width": "full"
  }
}

@danielmacedo90 - Could you please confirm if clicking on expand icon is giving blank screen? It gives blank screen until I switch to another chat and come back. Could you please confirm if you are facing the same?

@Meghana-MSFT - What about the image not being resized on the adaptive card when using the stretch size together with the allow expand? Has a bug ever been reported?

Thank you for your attention!
