砌体和无限滚动图像重叠

Question

我在我的网站上使用Masonry和Infinite Scroll来加载内容。但是，无论何时达到Infinite Scroll加载到新内容中的点，图像都会相互重叠。我已经尝试过所有我无法解决的事情。有什么想法吗？

HTML

<div id="container" class="js-masonry infinite-scroll" data-masonry-options='{ "isFitWidth": true }'>
    {% paginate blog.articles by 20 %}
      {% for article in blog.articles %}
          <div class="item">
            <div class="overlay">
                    <a href="{{ article.url }}">{{ article.content }}</a>
                </div>
          </div>
      {% endfor %}

      {% if paginate.next %}
        <div class="more"><a href="{{ paginate.next.url }}">More</a></div>
      {% endif %}
    {% endpaginate %}       
</div>

JS

$(window).load(function(){
  var $container = $('#container');
  $container.infinitescroll({
    navSelector  : '.more',    // selector for the paged navigation 
    nextSelector : '.more a',  // selector for the NEXT link (to page 2)
    itemSelector : '.item',     // selector for all items you'll retrieve
    loading: {
        finishedMsg: 'No more pages to load.',
        img: 'http://i.imgur.com/6RMhx.gif'
      }
    },
    // trigger Masonry as a callback
    function( newElements ) {
      var $newElems = $( newElements );
      $container.masonry( 'appended', $newElems, true );
        $container.masonry();
    }
  );
});
