JS File Structure panel doesn't see all the functions Follow

Hello,

When I create a js file, WebStorm can see all the var and function declarations properly if I write the code like this:

-----------------------

var app = (function ()
{
    var varA;
    var varB;


    function funcA()
    {}


    function funcB()
    {}


    return {
        funcA: funcA()
    };
})();
-----------------------

But when I split declaration and definition of app like this:

----------------------
var app;
app = (function () {...})();
----------------------
the structure panel shows only app>funcA but no vars and no funcB. Is it a bug or do I do something wrong?

(Also how do you set code to look like code in a post on this forum?)
