title: Swiper.js Loop: true not working when slidesPerView and slidesPerColumn set
body: <p>When using the very popular swiper.js, normally works as expected. However currently loop = true is not working because we have slidesPerView and slidesPerColumn enabled. </p>
  
  <p>Currently have:</p>
  
  <pre><code>var mySwiper = new Swiper ('#my-swiper', {
    slidesPerView: 3,
    slidesPerColumn: 2,
    spaceBetween: 30,
    speed: 2000,
    loop: true,
    autoplay: {
      delay: 1000,
      disableOnInteraction: false,
    },
  </code></pre>
  
  <p>Several others have ran into a similar issue but not clear solution. One noted they added to help resolve the issue: </p>
  
  <pre><code>setTimeout(function(){
      mySwiper.update(true);
      mySwiper.slideTo(0, 0)
  }, 100);
  </code></pre>
  
  <p>Tried adding after the above code block but they there is no motion at all. If I added it inside the above code block then it shows one large thumbnail per slide vs 6. Any thoughts?</p>
