Problem - defer function invokation till the full browser render and till the end of view-model synchronization cycle

script.js

var Ctrl = function ($scope, initAnchorScrolling) {
    initAnchorScrolling($scope);
};

Ctrl.$inject = ['$scope', "initAnchorScrolling"];

applicationServices.factory("initAnchorScrolling",
    ['scroll', '$location', '$timeout', function(scrollUtils, $location, $timeout) {
    return function(scope) {

    /** Some stuff here */

    function scroll() {
        var hash = $location.hash(), elm;

        if (!hash) {
            scrollUtils.scrollTo(0, 0);
        } else if ((elm = getAnchorElement(hash))) {
            scrollUtils.scrollToElement(elm);
        } else {
            scrollUtils.scrollTo(0, 0);
        }
    }

    scope.$watch(function scrollWatch() { return $location.hash(); },
        function scrollWatchAction() {
            $timeout(function () {
                scroll();
            }, 0, true);
        });
    };
}]);
