Alias resolution is invalid when using the emitDeclarationOnly option and the *.js extension.

// tsconfig.json
{
  "include": ["src"],
  "compilerOptions": {
    "outDir": "dist",
    "baseUrl": "src",
    "paths": {
      "@/*": ["./*"]
    },
    "declaration": true
  }
}

// src/b.ts
const b = "b";
export default b;

// src/a.ts
import b from "@/b";
import bb from "@/b.js"; // <-- *.js extension
export type t = typeof b;
export type tt = typeof bb;
console.log(b, bb);

---

// cli
tsc && tsc-alias

// dist/a.d.ts
import b from "./b";
import bb from "./b.js"; // <-- relative path
export declare type t = typeof b;
export declare type tt = typeof bb;

---

// cli
tsc --emitDeclarationOnly && tsc-alias

// dist/a.d.ts
import b from "./b";
import bb from "@/b.js"; // <-- alias path
export declare type t = typeof b;
export declare type tt = typeof bb;
