title: Fancybox 3.x.x have bug when somewhere on page div have min-height:100% property
body: <p>I just can't fix this. When one <code>div</code> on page have attribute <code>min-height:100%</code>; after click on some element with fancybox class, image shows, but page <strong>jump in Y</strong> for <strong>height of childs of div</strong> with <code>min-height:100%;</code></p>
  
  <p>Example:</p>
  
  <pre><code>body{height:100%;}
  html{height:100%;}
  
  some_class{
      min-height:100%;
      background-image:url();
      background-size:cover;
      background-position:center center;
  }
  
  some_absolute_div_in_some_class{
  
       position:absolute;
       width:200px;
       height:200px;
       top:50%;
   }
  </code></pre>
  
  <p>And then I put some position:absolute div-s in <code>some_class</code> div.</p>
  
  <p>Few div-s later when I build one page template, I put gallery with fancybox. And only when I remove <code>min-height:100% for some_class</code> - it works ok, with it <strong>whole page jump on Y asis</strong> after open fancybox.</p>
