Possiblily to display String as JSON in the Response samples block

Describe the problem to be solved
Is there any way to detect the media type application/json and display the JSON in the Response samples block?

For example

in this case, it works properly, it can display the JSON in the Response samples block

openapi: 3.0.1
info:
  title: Example
  version: 1.0.0
paths:
  /example:
    get:
      responses:
        "200":
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Config'
        "404":
          content:
            application/json:
              schema:
                type: object
                example: {'errors': [{'code': 'E001', 'message': 'NotFound'}]}
components:
  schemas:
    Config:
      type: object
      properties:
        name:
          type: string
      example: {'name': 'A'}

But in this case it will display as a plain text

openapi: 3.0.1
info:
  title: Example
  version: 1.0.0
paths:
  /example:
    get:
      responses:
        "200":
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Config'
        "404":
          content:
            application/json:
              schema:
                type: object
                example: "{'errors': [{'code': 'E001', 'message': 'NotFound'}]}"
components:
  schemas:
    Config:
      type: object
      properties:
        name:
          type: string
      example: "{'name': 'A'}"

Start by reproducing the two OpenAPI examples in the Response samples block and compare how object examples and string examples are rendered. Trace the Response samples implementation to see where the application/json media type is handled; done means JSON-looking string examples render as JSON while other plain-text examples remain text.
