Issue in "https://adaptivecards.io/designer" website

Hi Team,
While working on to the AdaptiveCards's designer website, I encountered an issue where when I create a design via using platform UI there were places in the Adaptive Card's code where data/property of fields are been added in Headline case, which is giving a warning in VS code.

Here's the code:

{
"$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
"type": "AdaptiveCard",
"version": "1.3",
"body": [
{
"type": "ColumnSet",
"columns": [
{
"type": "Column",
"width": "20px",
"minHeight": "0px",
"verticalContentAlignment": "Bottom",
"items": [
{
"type": "TextBlock",
"text": "$",
"spacing": "None", // Issue Here
"wrap": true,
"maxLines": 0,
"horizontalAlignment": "Center", // Issue Here
"weight": "Bolder", // Issue Here
"size": "Large" // Issue Here
}
],
"horizontalAlignment": "Center",
"spacing": "None" // Issue Here
},
{
"type": "Column",
"width": "stretch",
"items": [
{
"type": "Input.Number",
"id": "number",
"placeholder": "Enter a number",
"label": "Enter a number",
"min": 1,
"max": 1,
"value": 3,
"spacing": "None", // Issue Here
"isRequired": true,
"errorMessage": "please enter the quantity"
}
]
}
],
"spacing": "None", // Issue Here
"horizontalAlignment": "Center",
"style": "default"
}
],
"actions": [
{
"type": "Action.Submit",
"title": "Action.Submit"
}
]
}

Start at https://adaptivecards.io/designer and reproduce the reported card generation in the platform UI. Inspect the generated Adaptive Card JSON and the VS Code warnings around the highlighted properties. Done means the designer output uses the expected property casing and no longer produces those warnings.
