Steps to reproduce the bug

export interface Foo {
  type?: string;
  name?: string;
  id: string;
  hidden?: boolean;
}

export class Foo extends Serializable implements Foo {
  constructor(params: Foo) {
    super(params);
  }
}

The above example might look strange. Like this, the class Foo does not need to implement all the properties of interface Foo. The properties are just there (Mixin).

My assumption is, that this code leads to an endless loop.....or actually endless recursion of function function fullHierarchy(context, root)

Environment

• Typedoc version: 0.25.7
• TypeScript version: 5.1.6
• Node.js version: 21.6.1
• OS: Windows 11

Can confirm, I am seeing the same behaviour. MRE:

// index.ts
interface IAnimal {
  name: number;
}

interface IFish extends IAnimal {
  maxDepth: number;
}

class IFish implements IFish {}

Result:

$ npx typedoc index.ts

Unfortunately, I do not really know the purpose of such structures, but they exist (probably legacy code) and cause the issue mentioned above.

Huh, I guess that's valid TS... didn't think I had to worry about infinite loops when dealing with inheritance.
