How can I document a property defined with Object.defineProperties() in WebStorm (JSDoc)

Question

Let's say I define a property with Object.defineProperties(). If I try to specify the type of this property with a JSDoc comment, WebStorm gives me a warning.

Here is an example:

Object.defineProperties(obj, {

    /**
     * @type {String}
     */
    example: { get: function() { return 'example'; } }
}

This will give me the following WebStorm warning: Initializer type {get: Function} is not assignable to variable type String.

If I switch to the following, the warning goes away but the generated documentation does not say that a "string" is expected:

Object.defineProperties(obj, {

    /**
     * @type {get: Function}
     */
    example: { get: function() { return 'example'; } }
}

Any ideas on how to fix this ?
