title: Iframe doesn't show up on Chrome within Masonry CSS grid
body: <p>I've just noticed that when you create a CSS based masonry using <code>column-width</code> and put an iframe into it, The iframe doesn't show up in Chrome, however it works fine in other browsers.
  Is that a known bug in Chrome or lack of my code?
  Here is my HTML </p>
  
  <pre><code>&lt;section&gt;
    &lt;div class='block'&gt;
      &lt;img src='../images/mockup/jpg/1.jpg'&gt;
    &lt;/div&gt;
  &lt;/section&gt;
  </code></pre>
  
  <p>And here is the CSS </p>
  
  <pre><code>section {
    -moz-column-width: 15em;
    -webkit-column-width: 15em;
    column-width: 15em;
    -moz-column-gap: 1em;
    -webkit-column-gap: 1em;
    column-gap: 1em;
  }
  </code></pre>
