WebStorm Click navigate doesn't work with some directives

Hi,

I've noticed that click navigation doesn't work with some directives.
So far, it seems that this fails


    angular
        .module('first.UI')
        .directive('fdfAccordionHeading', fdfAccordionHeading);

    function fdfAccordionHeading() {

and this works


    angular
        .module('first.UI')
        .directive('fdfAccordionGroup', /*fdfAccordionGroup);*/

    function /*fdfAccordionGroup*/() {

Any idea on why this happens? Maybe I should open a bug request?

Thank you very much.
