JSDoc @name tag does not function

• VSCode Version: 1.33.1
• OS Version: Windows 7 x86_64 (but I do not think that is relevant)
• Does this issue occur when all extensions are disabled?: Yes

Steps to Reproduce:

1. Write in a file with .js or .ts extension the below sample code:

/**
  Construct a new component

  @class Component
  @classdesc A generic component

  @param {Object} options - Options to initialize the component with
  @param {String} options.name - This component's name, sets {@link Component#lastProperty}
  @param {Boolean} options.visible - Whether this component is vislble, sets {@link Component#firstProperty}
*/
function Component(options) {
  /**
    Whether this component is visible or not

    @name Component#firstProperty
    @type Boolean
    @default false
  */
  this.firstProperty = options.visible;

  /**
    This component's name

    @name Component#lastProperty
    @type String
    @default "Component"
    @readonly
  */
  Object.defineProperty(this, 'lastProperty', {
    value: options.name || 'Component',
    writable: false
  });
}

const myComponent = new Component({});

2. on a new line at the end of the document type myComponent with a dot at its end.
3. While the text-cursor is after the dot, press Ctrl+Space to open the auto-completion list.

Current Behavior:

When you chose .js as file extension, only firstProperty is in the auto-completion list (with its type comment and so on).

But when you have it in a file with .ts extension, none of firstProperty and lastProperty will be detected, and JSDoc seems useless.

Expected Behavior:

Both firstProperty and lastProperty should be detected and get placed in the auto-completion list, and that no matter which of .js or .ts file extensions we are using.

Reproduce the supplied Component example in both .js and .ts files, then inspect the completion behavior after myComponent.. Compare which JSDoc-defined properties are detected in each file type; done means both firstProperty and lastProperty appear in completion lists for both extensions.
