title: Swiper.js W3C AA keyboard tab issue
body: <p>I have a requirement to make a carousel using Swiper.JS to be W3C AA compliant.</p>
  <p>Issue i'm facing is if the tab each slider the slider gets broken, and the right arrow control is the middle of the carousel. Is there any way to automatically set the non visible slides with tabindex=&quot;-1&quot; or make the visibility hidden, so its not possible to tab to them?</p>
