oas3-valid-media-example not catching some bad example values

[pemba-sherpa-sage]

Describe the bug oas3-valid-media-example doesn't flag the stray field provided in the media example as an error

To Reproduce

1. Given this OpenAPI/AsyncAPI document (name.yaml)

   
   openapi: 3.0.0
   info:
   title: Sample API
   version: 1.0.0
   description: Sample OpenAPI Spec with a Schema

paths: /sample: get: summary: Get Sample Data responses: '200': description: Successful response content: application/json: schema: $ref: '#/components/schemas/SampleSchema' example: name: null # this is caught by the spectral rule dateOfBirth: 1990-01-01 status: test # this not caught by the spectral rule until the first error (name) is fixed age: 12 # this does not exist in the schema

components: schemas: SampleSchema: type: object properties: name: type: string example: John Doe dateOfBirth: type: string format: date example: 1990-01-01 status: type: string enum:

• active
• inactive example: active

2. the following spectral rule: (.spectral.yml)
```yaml
extends: spectral:oas

4. Run this CLI command '....'

   spectral lint --ruleset=.spectral.yml name.yaml

Expected behavior

• The rule should flag the stray field provided in the example (i.e age) since it does not exist in the schema
• If an example is bad, it stops at the first bad example and doesn't process others until you fix it. I believe it should catch all instead of fail on first for example evaluation

Environment (remove any that are not applicable):

• Spectral version 6.5.0
• OS: Darwin/Mac
