The below card (a simplified version of our Inputs.json card where the name field has been marked required) uses placeholders for labels. As a result there is no label to append the * indicator to and there is no indication that the input is required until after submit. Is this the desired behavior?

{
  "type": "AdaptiveCard",
  "version": "1.0",
  "body": [
    {
      "type": "TextBlock",
      "size": "medium",
      "text": "Please enter the following information:"
    },
    {
      "type": "Input.Text",
      "placeholder": "Name",
      "isRequired": true,
      "id" : "name",
      "errorMessage":"Name is required"
    },
    {
      "type": "Input.Text",
      "placeholder": "Homepage",
      "id": "homepage"
    },
    {
      "type": "Input.Text",
      "placeholder": "Email",
      "id": "EmailVal"
    },
    {
      "type": "Input.Text",
      "placeholder": "Phone",
      "id": "TelVal"
    }
  ],
  "actions": [
    {
      "type": "Action.Submit",
      "title": "Submit"
    }
  ]
}

we are not going to block the shipping but we should look back at it.

We've decided that this is the expected behavior. Using placeholders as labels is not a good practice in general, and card authors should use a label when marking inputs required. We will return warnings when a card author marks an input as required without including a label.
