[BUG] [Angular-Typescript] Not generating inheritances for allOf

When using the current version (https://editor.swagger.io/) with this YAML

        - $ref: '#/components/schemas/IHiddenBase'
      properties:
        a:
          type: string
          nullable: true
      additionalProperties: false
    IBase2:
      type: object
      properties:
        b:
          type: string
          nullable: true
      additionalProperties: false
    IHiddenBase:
      type: object
      allOf:
        - $ref: '#/components/schemas/IObject'
      properties:
        hid:
          type: string
          nullable: true
      additionalProperties: false
    IObject:
      type: object
      properties:
        id:
          type: string
          format: uuid
          readOnly: true
      additionalProperties: false
    IObjectX:
      type: object
      allOf:
        - $ref: '#/components/schemas/IBase1'
        - $ref: '#/components/schemas/IBase2'
      properties:
        x:
          type: string
          nullable: true
      additionalProperties: false

I get the following model with only IBase1 extended:

import { IBase1 } from './iBase1';
import { IBase2 } from './iBase2';

export interface IObjectX extends IBase1 { 
    b?: string;
    x?: string;
}

Guess that's an issue? Took me a while already to make Swashbuckle understand multiple interface inheritances, please don't tell me I'll fail now on generation.

Reproduce the issue in editor.swagger.io with the YAML and Angular-TypeScript output shown here. Trace the generator's allOf handling and verify that the generated IObjectX interface extends both IBase1 and IBase2 while preserving the listed properties.
