documentation request does not work for ClassDeclarations

[mrennie]

Consider the following snippet:

/**
 * @description This is a class decl that I figured I should talk about
 * @name MyClass
 * @since 1.0
 */
class MyClass {
	constructor() {}
}
export default MyClass;
export let instance = new MyClass();

If you issue a documentation request with the position in any of the 'MyClass' identifiers, no documentation is returned.
