💻 Code

/**
 * @import {
 *   Program
 * } from 'estree'
 */

/**
 * @param {Program} program
 */
export function compile(program) {}

🙁 Actual behavior

TypeScript emits the following type invalid definition:

/**
 * @import {
 *   Program
 * } from 'estree'
 */
/**
 * @param {Program} program
 */
export function compile(program: *   Program): void;
import type { Program } from 'estree';

🙂 Expected behavior

TypeScript emits the following valid type definition:

/**
 * @import {
 *   Program
 * } from 'estree'
 */
/**
 * @param {Program} program
 */
export function compile(program: Program): void;
import type { Program } from 'estree';
