title: Bootstrap 3.3.1 carousel animation not working with LESS
body: <p>I am working on a Bootstrap template that I am building on the Bootstrap 3.3.1 LESS files compiled on the go (as a temporary solution) with less.min.js. The problem is when I try to flip slides of the Bootstrap carousel they do so with no animation. Chrome Dev tools gave me this:</p>
  
  <pre><code>.carousel-inner &gt; .item {
    transition: transform 0.6s ease-in-out;
    backface-visibility: hidden;
    perspective: 1000;
  }
  </code></pre>
  
  <p>As you can see there is not -webkit-transition line for some reasons. </p>
  
  <p>Switching to bootstrap.css or replacing the carousel.less file with that from v3.3.0 resolves the issue. Is it a Bootstrap issue or is it something on my side?</p>
