                $waiting += 100000;
                usleep(100000);
            } while ($waiting < $timeoutMicroSeconds &&
                $session->execute(['script' => $isAjaxActive, 'args' => []]));
        });
    }

No, this is a helper method that you can use in your Acceptance suite instead of the plain "wait"
