SwiperSlider, Gallery with thumbs and loop enabled breaks SwiperSlider completly

SwiperSlider breaks with loop: true and thumbs enabled.

my code is this:

var galleryTop = new Swiper('.gallery-top', {
  spaceBetween: 15,
  slidesPerView: 2,
  centeredSlides: true,
  loop: true
});

var galleryThumbs = new Swiper('.gallery-thumbs', {
  spaceBetween: 10,
  centeredSlides: true,
  slidesPerView: 'auto',
  touchRatio: 0.2,
  slideToClickedSlide: true,
  loop: true
});

galleryTop.params.control = galleryThumbs;
galleryThumbs.params.control = galleryTop;

a working example of the problem is here: http://ift.tt/2fYrVQx

I didn't expect the result with loop: true, when I set it to false, the slider works great.

Does anyone have a solution for this?
