Expected Behavior

Expected upgrading from typedoc@0.23.25 to typedoc@0.28.15 to continue producing documentation

Actual Behavior

After upgrading, typedoc@0.28.15 fails with [error] Tried to get a URL of a router target lib/Helpers.Helpers.catchIfCatchable.catchIfCatchable.__type.__type which did not receive a URL

Steps to reproduce the bug

Seems to have something to do with Promise types

export class TypeDocBugPromise<T> implements Promise<T> {
	public readonly [Symbol.toStringTag] = "Promise";
	public then():    any {}
	public catch():   any {}
	public finally(): any {}
}

export class TypeDocBugClass {
	public static catchIfCatchable( p: any ): typeof Promise.prototype.catch | undefined {
		throw "Minimizing for bug reproduction";
	}
}

I didn't try to minimize the tsconfig in place, here's just the typedocOptions:

	"typedocOptions": {
		"entryPointStrategy": "expand",
		"entryPoints": ["src"],
		"out": "doc",
		"includeVersion": true,
		"validation": {
			"notDocumented": true,
		},
	},

... and the whole thing collapsable
