Adaptive Card Title alignment problem in New Teams Application

Question

We are sending adaptive card from the application. Sometime for some user we noticed that adaptive card sent has broken header.

It actually showing icon, title and menu in stack instead of one line.

Below is adaptive card which we are using.

{
"type": "AdaptiveCard",
"msTeams": {
  "width": "full"
},
"metadata": {
  "webUrl": "${applicationURL}"
},
"body": [
 {
  "type": "ColumnSet",
  "columns": [
    {
      "type": "Column",
      "items": [
        {
          "type": "TextBlock",
          "size": "Medium",
          "weight": "Bolder",
          "text": "[${cardTitle}](${applicationURL})"
        },
        {
          "type": "TextBlock",
          "size": "Medium",
          "weight": "Bolder",
          "text": "${answerCount} ${answers} & ${voteCount} ${votes}"
        },
        {
          "type": "TextBlock",
          "weight": "default",
          "text": "${description}",
          "wrap": true
        },
        {
          "type": "TextBlock",
          "weight": "default",
          "text": "${source}",
          "wrap": true
        }
      ],
      "width": "stretch"
    }
  ]
}
],
"$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
"version": "1.4"
}

This given below like output. Kindly suggest what's wrong here.

Update: 13 Feb

I have noticed issue in the Old teams as well. Here when collaborative StageView is open loop based adaptive card is broken which was showing perfectly in the normal chat. Now this one you can reproduce as its happening every time for me. Attaching image for your refs.
