autoplay: false displays preloader so users can't control the player

When user add this parameter "autoplay: false" to options, video doesn't start and preloader appears. Preloader blocks all of the controls because of its z-index. So people can't start the video.

Start by locating the autoplay option handling and the preloader element or its z-index, then reproduce the issue with autoplay set to false. Done means the preloader no longer blocks the player controls and users can start the video manually.
