The function cancelFullScreen needs to be changed.

  function cancelFullScreen () {
	if (that.fullScreen) {
	  that.fullScreen = false;
	  if (FULLSCREEN && that.fullScreen) {
		fullScreenApi.cancel(fotorama);
	  }

	  $BODY.removeClass(_fullscreenClass);
	  $HTML.removeClass(_fullscreenClass);

	  $fotorama
		  .removeClass(fullscreenClass)
		  .insertAfter($anchor);

	  measures = $.extend({}, measuresStash);

	  unloadVideo($videoPlaying, true, true);

	  updateTouchTails('x', false);

	  that.resize();
	  loadImg(activeIndexes, 'stage');

	  lockScroll($WINDOW, scrollLeft, scrollTop);

	  triggerEvent('fullscreenexit');
	}
  }
