allOf does not pass the openapi schema check for "valid" required scenarios

[califlower]

We have some specs (that I don't agree are good specs per se) that are technically valid but aren't passing oas-schema-check.
For example:

   CloudAppDataset:
      allOf:
      - $ref: '#/components/schemas/CloudAppDatasetCreate'
      - type: object
        required:
        - datasetId
        - status
        properties:
          datasetId:
            type: string
            minLength: 1
            maxLength: 50
            description: Unique identifier for the CloudApp dataset.
            example: tdi_dataset_01n2xcejqtf2nbrexx3vqjhp15

throws

#0 251.3 Rule: oas-schema-check
#0 251.3 - Severity: error
#0 251.3 - Message: `required` field `status` is not defined in `properties`
#0 251.3 - Path: $.components.schemas['WarehouseDataset'].allOf[1].required[1]
#0 251.3 - How to fix:
#0 251.3 Make sure each schema has a value type defined. Without a type, the schema is useless

technically required is only checkable on the instance of an object (which is a whole other thing and means you can't really check it at build time), but I think for the spirit of this schema checker is that at least for allOf it needs to check the completed object not just each arm
