Description

Adaptive inputs of type Input.Number don’t display the value 0.

To Reproduce

Steps to reproduce:

1. Go to Adaptive Cards Designer
2. Select Bot Framework WebChat as the host app
3. Paste the following json in the Card Payload Editor:

{
    "type": "AdaptiveCard",
    "actions": [
      {
        "title": "Submit",
        "type": "Action.Submit"
      }
    ],
    "body": [
      {
        "text": "Input 1",
        "type": "TextBlock"
      },
      {
        "id": "InputOne",
        "placeholder": "Input 1 Placeholder",
        "type": "Input.Number",
        "value": 10
      },
      {
        "text": "Input 2",
        "type": "TextBlock"
      },
      {
        "id": "InputTwo",
        "placeholder": "Input 2 Placeholder",
        "type": "Input.Number",
        "value": -10
      },
      {
        "text": "Input 3",
        "type": "TextBlock"
      },
      {
        "id": "InputThree",
        "placeholder": "Input 3 Placeholder",
        "type": "Input.Number",
        "value": 0
      }
    ],
    "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
    "version": "1.0"
}

1. See that the third input is not displaying the expected value

Additional Info

This card was created using the C# AdaptiveCards package 1.2.0 This card will render correctly in the Emulator

[Bug]

I was able to reproduce this by sending the same json to Mock Bot for rendering

copy-pasting the json to the Adaptive Cards schema reproduces this issue, but manually assigning the value 0 in the schema editor shows the value 0 as expected.
