jQuery SVG анимация не завершена

Question

Я создал анимацию на веб-сайте для клиента.Мне было интересно, почему на некоторых экранах (как правило, меньше) код не завершен.Большое спасибо.

Это сайт (для перенаправления на реальный сайт потребуется секунда ... Я не хочу, чтобы это показывалось в их SEO): https://dereferer.me/?oh4N0vg2vr-okGm8mpEb5m_O4pEvk3rpvK

Строка должна быть заполнена в контактной форме внизу страницы (она отображается только на рабочем столе).

Я несколько раз пытался изменить некоторые расчеты, но очень важно, чтобы путь выгляделточно так же.
