title: text-align: justify; not working with wkhtmltopdf
body: <p>I'm creating PDF docs from HTML using wkhtmltopdf library. I used svg font according to this issue <a href="https://stackoverflow.com/questions/25908298/wkhtmltopdf-custom-font-letter-spacing">wkhtmltopdf custom font letter spacing</a></p>
  <p>I used a custom font, and added it by @font-face.
  All works fine for me, except for <code>text-align: justify</code> is not working for some reason.</p>
  <p>In HTML text is aligned as expected, but not in PDF.</p>
  <p>Is anyone know how to fix this issue?</p>
  <p><strong>UPD</strong>: Added CSS and HTML example</p>
  <pre><code>&lt;style type=&quot;text/css&quot;&gt;
      @font-face{
          font-family:'source_sans_prolight';
          src: url('/font/sourcesanspro-light-webfont.svg') format('svg');
          font-weight:normal;
          font-style:normal;
      }
  
      @font-face{
          font-family:'Source Sans Regular';
          src: url('/font/sourcesanspro-regular-webfont.svg') format('svg');
          font-weight:normal;
          font-style:normal;
      }
      html, body, p, ul, li, span, img {
          margin: 0px;
          padding: 0px;
      }
  
      body {
          font-family: &quot;Source Sans Regular&quot;, sans-serif;
          text-rendering: geometricPrecision;
      }
      .page {
          width: 729px;
      }
      .block {
          width: 300px;
          float: left;
          margin-right: 40px;
          text-align: justify;
      }
  &lt;/style&gt;
  &lt;div class=&quot;page&quot;&gt;
      &lt;div class=&quot;block&quot;&gt;Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque fermentum iaculis mollis. Cras in varius lectus. Mauris consequat vestibulum dolor pretium pulvinar.&lt;/div&gt;
