Support ES6 class property type annotation by comment

Currently you can do this

/**@type {number} myVar */
var myVar = something

👍 Very cool as sometime intellisense needs help, but we can't do this

class MyClass {
    // Not working
    /**@type {number} myProp */
    myProp

    // Not working either
    /**@property {number} myProp2 */
    myProp2
}

Would be great if supported.

Thanks

This seems to be working for me on the latest version of typescript (2.7) + VS Code (1.12.1).
