Почему mouseleave и mouseout не работают с событием на вкладке bootstrap в Chrome?

Я работаю над настройкой этого примера с учетом бутстрапа. То, что я хотел, - это циклически перемещать вкладки, как слайдер, когда пользователь наводит курсор на значок со стрелкой влево/вправо. Наряду с этим я также хотел, чтобы ползунок продолжал ездить на велосипеде, если пользователь продолжает парить над иконкой со стрелкой влево/вправо. Я написал для этого следующий код:

(function() {


  function changeTab() {

    console.log("mouseenterd on ", $(this));

    if ($(this).closest("li").hasClass("next") && !$(this).closest("li").hasClass("hovered")) {
      $(this).closest(".nav-tabs").children("li").removeClass("hovered");
      $(this).tab('show');
    } else if ($(this).closest("li").hasClass("prev") && !$(this).closest("li").hasClass("hovered")) {
      $(this).closest(".nav-tabs").children("li").removeClass("hovered");
      $(this).tab('show');
    }
  }

  function outOfHover() {

    console.log("mouseleave on ", $(this));

    if ($(this).closest("li").hasClass("hovered")) {
      $(this).closest(".nav-tabs").children("li").removeClass("hovered");
    }

  }




  $('[data-toggle="tab"], [data-toggle="pill"]').on('mouseleave', outOfHover); //removes class hovered
  $('[data-toggle="tab"], [data-toggle="pill"]').on('mouseenter', changeTab); //runs bootstrap tabs like slider

  var triggerClickTab;
  var triggerClickCarousel;

  function triggerClick(that) {
    $(that).tab('show');
    console.log("show triggered " + " ", $(that));
  }

  $('[data-toggle="tab"], [data-toggle="pill"]').on('mouseenter', function() {
    var that = this;
    triggerClickTab = setInterval(triggerClick, 1650, that);
  });

  $('[data-toggle="tab"], [data-toggle="pill"]').on('mouseleave', function() {
    clearInterval(triggerClickTab);
  });



  $("#myCarousel .carousel-control").on('mouseenter', function() {

    if ($(this).hasClass("left")) {
      $("#myCarousel").carousel('prev');
    } else if ($(this).hasClass("right")) {
      $("#myCarousel").carousel('next');
    }

    var that = this;
    triggerClickCarousel = setInterval(triggerClick, 1650, that);
  });

  $("#myCarousel .carousel-control").on('click', function() {

    clearInterval(triggerClickCarousel);

    var that = this;
    triggerClickCarousel = setInterval(triggerClick, 1650, that)
  });

  $("#myCarousel .carousel-control").on('mouseleave', function() {
    clearInterval(triggerClickCarousel);
  });

  /* end if Condition for non-touch device finsihes here */

  $(document).on('show.bs.tab', '.nav-tabs [data-toggle="pill"], .nav-tabs [data-toggle="tab"]', function(e) {
    var $target = $(e.target);
    var $tabs = $target.closest('.nav-tabs');
    var $current = $target.closest('li');
    var $parent = $current.closest('li.dropdown');
    $current = $parent.length > 0 ? $parent : $current;
    var $next = $current.next();
    var $prev = $current.prev();

    var updateDropdownMenu = function($el, position) {
      $el
        .find('.dropdown-menu')
        .removeClass('pull-left pull-center pull-right')
        .addClass('pull-' + position);
    };

    $tabs.find('>li').removeClass('hovered');

    if ($current.hasClass("next")) {
      $next.addClass('hovered');

    } else if ($current.hasClass("prev")) {
      $prev.addClass('hovered');
    }

    $tabs.find('>li').removeClass('next prev');
    $prev.addClass('prev');
    $next.addClass('next');

    updateDropdownMenu($prev, 'left');
    updateDropdownMenu($current, 'center');
    updateDropdownMenu($next, 'right');
  });



}());

Известно, что Chrome не обрабатывает какое-либо событие мыши, если курсор не перемещается. Что-то связано с оптимизацией пользовательского интерфейса.

Одним из способов обхода может быть принудительное выполнение каждого обратного вызова интервала при перерисовке пользовательского интерфейса. Существует много способов принудительного переназначения, один из которых состоит в том, чтобы перерисовать сам элемент, например:

function triggerClick(that) {                    
    $(that).tab('show').hide().show(0); // force a repaint
    console.log("show triggered " + " ", $(that));
}
