Validation fails when default is set as object property

[luzeno]

Describe the bug
The oas validation fails when the default property is set as an object property, but it doesn't cover all the required values:

38:15 error oas3-valid-schema-example "default" property must have required property "count" components.schemas.Foo.default.

To Reproduce

1. Given this OpenAPI document and Spectral configuration

api.yaml

openapi: 3.0.3
info:
  title: Sample API
  version: 0.1.0

paths:
  /test:
    post:
      requestBody:
        description: Optional description in *Markdown*
        required: true
        content:
          application/json:
            schema:
              $ref: '#/components/schemas/Foo'
      responses:
        "200": # status code
          description: Sample response
          content:
            application/json:
              schema:
                type: array
                items:
                  type: string

components:
  schemas:
    Foo:
      type: object
      properties:
        name:
          type: string
        count:
          type: integer
      required:
        - name
        - count
      default: # <--- Failing because 'default' doesn't contain the 'count' property that is required
        name: foo

.spectral.yaml

extends: ["spectral:oas"]

2. Run this command: spectral lint api.yaml
3. Validation fails with the following error:

38:15 error oas3-valid-schema-example "default" property must have required property "count" components.schemas.Foo.default

Expected behavior
The validation should pass since it is compliant with the json schema validation and the oas specification.

Environment:

• Library version: 6.14.2

Additional context
The validation works fine for the given OpenAPI document using the swagger editor online.
