💻 Code

Input

function x() {
    function u() {}

    /**
     * lol
     */
    function y() { }

    return {
        u,
        y,
        /**
         * lol2
         */
        z() { }
    }
}

Output .d.ts

declare function x(): {
    u: () => void;
    y: () => void;
    /**
     * lol2
     */
    z(): void;
};

🙁 Actual behavior

In the above example, the .d.ts files won't contain y's JSDoc, but only z's.

🙂 Expected behavior

Both JSDoc are preserved.
