Inheritance is not processed correctly for generated Interfaces

[Andy2003]

For the following API

openapi: 3.0.0
info:
  version: '1.0'
  title: Testinheritance
paths:
  /cat:
    post:
      requestBody:
        content:
          '*/*':
            schema:
              $ref: '#/components/schemas/Cat'
      responses:
        200:
          description: OK
components:
  schemas:
    Pet:
      type: object
      discriminator:
        propertyName: dtype
      properties:
        name:
          type: string
    Cat:
      type: object
      allOf:
        - $ref: '#/components/schemas/Pet'

This code is generated:

Spring:

ResponseEntity<Void> catPost(@ApiParam(value = ""  )  @Valid @RequestBody Object body);

Java:

public com.squareup.okhttp.Call catPostCall(Object body, final ProgressResponseBody.ProgressListener progressListener, final ProgressRequestBody.ProgressRequestListener progressRequestListener) throws ApiException

Typescript-Angular:

public catPost(body?: any, observe?: 'body', reportProgress?: boolean): Observable<any>;

The body param is of type Object instead of Cat

I am seeing this too in both v2 and v3. Interestingly, it determines the schema just fine if used in the response body.
