Mock generation doesn't guarantee the required property mocking about orval

[AffeJonsson]

Seems to be an issue when using oneOf in nested objects, regardless of if the properties are required or not

          content:

      properties:
        prop:
          type: string
    Item1:
      type: object
      oneOf:
        - $ref: '#/components/schemas/Item11'
        - $ref: '#/components/schemas/Item12'
      properties:
        prop1:
          type: string
    Item11:
      type: object
      properties:
        prop11:
          type: string
    Item12:
      type: object
      properties:
        prop12:
          type: string

yields

export const getCreateItemsResponseMock = (overrideResponse: any = {}): Item =>
  faker.helpers.arrayElement([
    {
      prop11: faker.word.sample(),
      ...overrideResponse,
      prop1: faker.word.sample(),
      ...overrideResponse,
/*
Here we are missing these:
      prop: faker.word.sample(),
      ...overrideResponse,
*/
    },
    {
      prop12: faker.word.sample(),
      ...overrideResponse,
      prop1: faker.word.sample(),
      ...overrideResponse,
      prop: faker.word.sample(),
      ...overrideResponse,
    },
  ]);

Unsure how to fix this as it seems like prop: faker.word.sample(), ...overrideResponse, is added to the string

    {
      prop11: faker.word.sample(),
      ...overrideResponse,
      prop1: faker.word.sample(),
      ...overrideResponse,
    },
    {
      prop12: faker.word.sample(),
      ...overrideResponse,
      prop1: faker.word.sample(),
      ...overrideResponse,
