oneOf not on root is not shown in json samples

[albertored]

I'm using version 2.0.0.rc41

When a response consists of a schema with some oneOf elements not at root level only the first possibility is shown on json sample panel.

openapi: 3.0.0
info:
  version: '1.0'
  title: Test
security: []
paths:
  '/test':
    post:
      operationId: test
      responses:
        '201':
          description: Created
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/S'
components:
  schemas:
    S:
      type: object
      properties:
        p1:
          oneOf:
            - $ref: '#/components/schemas/S1'
            - $ref: '#/components/schemas/S2'
    S1:
      type: string
    S2:
      type: integer

If instead the oneOf element is at the root of the response the json sample correctly shows the switching schema buttons.

Unfortunately, this is not supported yet.
Hopefully, I'll get this working soon.
