[BUG] 5.2 Typescript not generating inheritances for allOf

When using the latest version (5.2) with this command:

docker run -v "[output]":/out openapitools/openapi-generator-cli generate -i http://host.docker.internal:64483/swagger/v1/swagger.json -g typescript-angular -o ./out

...
  "IObject": {
	"type": "object",
	"allOf": [
	  {
		"$ref": "#/components/schemas/IBase1"
	  },
	  {
		"$ref": "#/components/schemas/IBase2"
	  }
	],
	"properties": {
	  "x": {
		"type": "string",
		"nullable": true
	  }
	},
	"additionalProperties": false
  },
  "IBase1": {
	"type": "object",
	"properties": {
	  "a": {
		"type": "string",
		"nullable": true
	  }
	},
	"additionalProperties": false
  },
  "IBase2": {
	"type": "object",
	"properties": {
	  "b": {
		"type": "string",
		"nullable": true
	  }
	},
	"additionalProperties": false
  }
...

IObject gets the related interfaces linked, but does not extend them:

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


export interface IObject { 
    x?: string | null;
    a?: string | null;
    b?: string | null;
}

but that’s the result I’d love to see:

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

export interface IObject extends IBase1, IBase2 { 
    x?: string | null;
}

Please don’t tell me this isn’t possible! It took me already a hell of work to make my own Swashbuckle fork understand Interface inheritances.

The specification tells nothing about discriminator is mandatory! https://swagger.io/docs/specification/data-models/oneof-anyof-allof-not/

Quote: OpenAPI lets you combine and extend model definitions using the allOf keyword. allOf takes an array of object definitions that are used for independent validation but together compose a single object. Still, it does not imply a hierarchy between the models. For that purpose, you should include the discriminator.

So, when hierarchy is not important or the allof array does only have one element no discriminator is needed.

For me this is a bug!

But we are just talking about models here! If they are used with a discriminator behind the curtain is a different thing! I just want my models to be generated clean & corrent!

No hope for it to come back? Is there anything I can do about it?
