• VSCode Version: 1.24.1 AND 1.25.0 (nightly build)
• OS Version: Ubuntu 16.04

Steps to Reproduce:

1. Create a .js file
2. Post the following code into the file and save

/**
  * @typedef {object} typeTest
  * 
  * @property {string} second - second property
  * @property {object} first - first property
  * @property {string} first.one - first's one property
  * @property {object} third - third property
  */

/**
 * @type typeTest
 */
const test;

3. third property becomes a property of first instead of a property of typeTest
