jsdoc doesn't correctly support namepath

Steps to Reproduce:

1. Create a js file with this code:

// my-new-type.js

/**
 * MyNewType
 * @typedef {Object} MyNewType
 * @property {Factory~logFirst} logFirst
 * @property {Factory~logSecond} logSecond
 */

/**
 * MyNewType factory
 * @constructor
 * @param {number} first
 * @param {number} second
 * @returns MyNewType
 */
function Factory(first, second) {
  /**
   * logs first argument
   * @param {number} times
   */
  function logFirst(times) {
    for (let i = 0; i < times; i++) {
      console.log(first);
    }
  }

  /**
   * logs second argument
   * @param {number} times
   */
  function logSecond(times) {
    for (let i = 0; i < times; i++) {
      console.log(second);
    }
  }

  return {
    logFirst,
    logSecond
  };
}

module.exports = Factory;

2. put the mouse over the MyNewType definition and see, that logFirst and logSecond are not defined:
   

What is expected - definitions of these functions are taken directly from the Factory object's inner definitions. The syntax is correct, since if I do jsdoc my-file.js the generated documentation correctly links these types together:

Here is the namepath documentation: http://usejsdoc.org/about-namepaths.html

Does this issue occur when all extensions are disabled?: Yes
