Some JSDoc tags aren't properly caught in VS Code

[CG-Tespy]

Issue Type: Bug

Create a new file, and copy-paste the following code:

/**
 * @namespace Foo
 */
var Foo;

/**
 * @type {number[]}
 */
var Working;

/**
 * @function Bar
 */
var Bar;

/**
 * @class Bar2
 */
var Bar2;

Now under that code in the file, try typing out the names of the variables. Intellisense will note the tags, but still classify the variables as undefined. That is, except for the var named "Working"; Intellisense sees that as the specified type, despite the actual value being undefined like the rest.
