Nested objects flattening loose lot of information ("required" for example)

[MercurieVV]

When I use nested objects (without reference), flattening phase loose lot of info from it. For example "required"

  schemas:
    ReturnInformation:
      type: object
      properties:
        manufacturer_signin_credentials:
          type: object
          properties:
            login:
              type: string
            password:
              type: string
          required:
            - login
            - password

geberate ReturnInformationManufacturerSigninCredentials which fields are optional, but should be required from spec.
I found its ahppening during flattening phase. In InlineModelResolver.modelFromProperty() method which copy only few properties.
