Current Behavior

There is a problem with nested if...then conditions inside properties. With liveOmit and omitExtraData enabled, the value of a property that is displayed conditionally is automatically removed.

Here is the JSON schema I am testing:

{
  "type": "object",
  "properties": {
    "object": {
      "title": "Object",
      "type": "object",
      "properties": {
        "name": {
          "title": "Name",
          "type": "string"
        },
        "booleanProperty": {
          "title": "Boolean Property",
          "default": true,
          "type": "boolean"
        }
      },
      "if": {
        "properties": {
          "booleanProperty": {
            "const": true
          }
        }
      },
      "then": {
        "properties": {
          "otherProperty": {
            "title": "Other Property",
            "type": "string",
            "enum": [
              "Hello",
              "World"
            ]
          }
        },
        "required": [
          "otherProperty"
        ]
      }
    }
  }
}

When the booleanProperty is set to true, the otherProperty field is displayed in the form, but its value cannot be changed because it is automatically cleared.

Expected Behavior

The value of otherProperty should not be cleared when booleanProperty is set to true.

Steps To Reproduce

1. Go to Playground.
2. Try to change Other Property value.

Essentially a re-open of #4109. @anya92 do you feel comfortable updating the fix the @helen-m-lin provided? Or maybe they can continue improving the fix?
