   прилипания ограничена высотой его же строки (максимум из двух колонок).
   У всех текущих товаров описание короче фото, инфо-колонка ниже галереи,
   строка подгоняется под саму галерею — запас на sticky нулевой, и фото
   просто едет вместе со страницей рывком вместо фиксации. Убрали sticky
   совсем — обычный скролл в потоке, без рывков и без искусственного
