Webstorm find symbol not working properly for function variables

I have a file wrapped in a closure and it has various support methods for a class not available on the class prototype
(function(){
  function thisFunctonWorksFine() {
  }

  var iAmInvisible = function() {
  };

  var iAmAlsoInvisible = function iAmAlsoInvisible() {
  };
}())

when using go to symbol (default CTRL+SHIFT+ALT+N) the first function is detected while the second and third are completely invisible.  Is this by design?  I know there is a find in file structure but I feel that should be part of the find symbol functionality.  Also the ability to restrict it to the current file is something I'd like to see.
