Default value does not work within anyOf PG

[goralight]

Prerequisites

• I have read the documentation;
• In the case of a bug report, I understand that providing a SSCCE example is tremendously useful to the maintainers.
• Ideally, I'm providing a sample JSFiddle or a shared playground link demonstrating the issue.

Description

When using anyOf, the default value does not get set correctly. This can be seen on the example PG for anyOf

Steps to Reproduce

1. Go to PG link
2. Select anyOf button
3. Notice how the default value is set for Chuck and Norris. Yet on the form data and on the preview, it has not populated the values

Expected behavior

Defaults within anyOf populate the data and preview

Actual behavior

Defaults within anyOf do not populate data or preview

Version

I am using the online PG for now. Example of Json Is below:

  "type": "object",
  "properties": {
    "age": {
      "type": "integer",
      "title": "Age"
    },
    "items": {
      "type": "array",
      "items": {
        "type": "object",
        "anyOf": [
          {
            "properties": {
              "foo": {
                "type": "string"
              }
            }
          },
          {
            "properties": {
              "bar": {
                "type": "string"
              }
            }
          }
        ]
      }
    }
  },
  "anyOf": [
    {
      "title": "First method of identification",
      "properties": {
        "firstName": {
          "type": "string",
          "title": "First name",
          "default": "Chuck"
        },
        "lastName": {
          "type": "string",
          "title": "Last name"
        }
      }
    },
    {
      "title": "Second method of identification",
      "properties": {
        "idCode": {
          "type": "string",
          "title": "ID code"
        }
      }
    }
  ]
}

I know this has apparently been done:
#1304

But within the PG it is still not working correctly.
