oneOf with objects containing null object refuses the selection of the null option

Prerequisites

• I have searched the existing issues
• I understand that providing a SSCCE example is tremendously useful to the maintainers.
• I have read the documentation
• Ideally, I'm providing a sample JSFiddle, Codesandbox.io or preferably a shared playground link demonstrating the issue.

Current Behavior

I have the following schema:

{
  "type": "object",
  "title": "Configuration",
  "oneOf": [
    {
      "title": "Default Configuration",
      "type": "object",
      "properties": {
        "types": {
          "const": "default",
          "title": "Types"
        },
        "content": {
          "type": "string",
          "title": "Content"
        }
      },
      "required": [
        "types"
      ]
    },
    {
      "title": "Advanced Configuration",
      "type": "object",
      "properties": {
        "types": {
          "const": "advanced",
          "title": "Types"
        },
        "content": {
          "type": "string",
          "title": "Content"
        }
      },
      "required": [
        "types"
      ]
    },
    {
      "title": "No Configuration",
      "type": "null"
    }
  ],
  "default": {
    "types": "advanced",
    "content": "placeholder"
  }
}

See playground
Note: We set "Object fields default behavior" to option "Assign value to formData when only default is set"

Current Behaviour:
No Configuration can not be selected from the dropdown.

Expected Behavior

No Configuration can be selected from the dropdown.

Steps To Reproduce

1. Open the playground link
2. Set "Object fields default behavior" to option "Assign value to formData when only default is set"
3. In the resulting form, try to set the Configuration to No Configuration
