Self referential types fail to compile

[chitalian]

Description

Having a self referential type like...

		"Json": {
				"anyOf": [
					{
						"type": "string"
					},
					{
						"type": "number",
						"format": "double"
					},
					{
						"type": "boolean"
					},
					{
						"properties": {},
						"additionalProperties": {
							"$ref": "#/components/schemas/Json"
						},
						"type": "object"
					},
					{
						"items": {
							"$ref": "#/components/schemas/Json"
						},
						"type": "array"
					}
				],
				"nullable": true
			},

Causes typescript to be generate like this

export interface components {
  schemas: {
    Json: (string | number | boolean | {
      [key: string]: components["schemas"]["Json"];
    } | components["schemas"]["Json"][]) | null;

Causing this failure...

./lib/clients/jawnTypes.ts:34:5
Type error: 'Json' is referenced directly or indirectly in its own type annotation.

  32 |       phoneNumbers: string[];
  33 |     };
> 34 |     Json: (string | number | boolean | {
     |     ^
  35 |       [key: string]: components["schemas"]["Json"];
  36 |     } | components["schemas"]["Json"][]) | null;
  37 |     /** @enum {string} */

Name	Version

Reproduction

openapi-typescript  swagger.json -o types.ts

Expected result

We can somehow build the typescript to move any self-referential types to it's own type like this?

type JsonValue = string | number | boolean | null | JsonArray | JsonObject;
interface JsonArray extends Array<JsonValue> {}
interface JsonObject {
  [key: string]: JsonValue;
}

export interface components {
  schemas: {
    User: {
      /** Format: double */
      id: number;
      email: string;
      name: string;
      /** @enum {string} */
      status?: "Happy" | "Sad";
      /** @enum {string} */
      status2?: "Happy" | "Sad";
      phoneNumbers: string[];
    };
    Json: JsonObject;

Similar problem here. The (reduced) code looks like this:

    PackageTreePermittedResponseV2: WithRequired<{
      permission: "FULL";
    } &  Omit<components["schemas"]["PackageTreeResponseV2"], "permission"> & ({
      packages?: components["schemas"]["PackageTreeResponseV2"][];
    }), "id" | "permission" | "packages">;
    PackageTreeResponseV2: {
      id: string;
      permission: string;
    } & (components["schemas"]["PackageTreePermittedResponseV2"]);
