title: Empty items with Owl Carousel if tabbing with keyboard to links inside items
body: <p>I'm using the current stable release of Owl Carousel (1.3.2) for a single item carousel. I have previous and next buttons enabled.</p>
  
  <p>A couple of the items within the carousel have links e.g. <code>&lt;a href="page.html" class="button"&gt;Find out more&lt;/a&gt;.</code></p>
  
  <p>When using the keyboard (in Chrome) to tab through the web page, the links inside the carousel obtain focus which is great. However, if the user then uses the previous and next buttons with a mouse to move to the next carousel item, it's empty. All other carousel items after the one containing the link inside it are empty also. No content at all.</p>
  
  <p>When inspecting the carousel using Chrome's DevTools, it actually looks like the carousel isn't moving along even though the links inside an item is focused and visible. it appears to be getting really confused.</p>
  
  <p>Has anyone experienced this sort of thing with Owl Carousel (or any other carousel) before? Is there anything I could try to get the carousel to move on properly if a link inside an item obtains focus?</p>
