title: border-image not working in mozilla
body: <p>I am applying <code>border-image</code> using <code>css</code> like below:</p>
  
  <pre><code> border-image: url('/assets/btn-border.png') 10 10 10 10;
  </code></pre>
  
  <p>It is working fine for Chrome but in Mozilla the border isn't appearing.</p>
  
  <p>I tried to use <code>.gecko</code> to that class but that didn't work.</p>
  
  <p>What's the issue here?</p>
