@interface type references do not always link correctly.

[Gerrit0]

TypeDoc's type convert doesn't appear to always capture symbols related to types when converting references.

Expected Behavior

The produced Bar interface should have a member whose type is Color, which is linked to the enum.

Actual Behavior

The produced Bar interface contains a member whose type is Color, without a link to the Color enum.

Steps to reproduce the bug

export enum Color {
    BLUE = "Blue",
    RED = "Red",
}

type TypeOf<T> = {
    [K in keyof T]: T[K][keyof T[K]];
};

type Foo = {
    color: typeof Color;
};

/** @interface */
export type Bar = TypeOf<Foo>;
//   ^?

Environment

• Typedoc version: 0.25.8
• TypeScript version: 5.3.2
• Node.js version: 20
• OS: Fedora

Initial investigation here indicates that TypeDoc is doing the right thing. Tossing that into https://ts-ast-viewer.com, clicking on Bar, and running checker.getTypeOfSymbolAtLocation(checker.getPropertiesOfType(type)[0]) returns a ts.Type whose aliasSymbol is not set.

TypeScript obviously knows what the type should be named here though, so I've asked in the #ts-compiler-api channel on the TS discord, maybe one of the TS devs will tell me what incantation is necessary to extract this info.
