💻 Code

/**
 * @template {string} Element
 * @overload
 * @param {Element} element
 * @returns {() => void}
 */

/**
 * @template {boolean} Element
 * @overload
 * @param {Element} element
 * @returns {() => void}
 */

/**
 * @overload
 * @param {number} element
 * @returns {() => void}
 */

/**
 * @param {any} element
 */
export function on(element) {
	return () => {}
}

🙁 Actual behavior

The resulting dts of the given JSDoc looks like this:

export function on<Element extends string>(element: Element): () => void;
export function on<Element extends string>(element: Element): () => void;
export function on(element: number): () => void;

As you can see the generic does extends string both times, but it should be extends boolean the second time

🙂 Expected behavior

export function on<Element extends string>(element: Element): () => void;
export function on<Element extends boolean>(element: Element): () => void;
export function on(element: number): () => void;
