code: function checkHovers(pageX, pageY) {
          $dropdown.children().each(function () {
              var offset = $(this).offset(),
                  width  = $(this).outerWidth(),
                  height = $(this).outerHeight();
  
              if (pageX >= offset.left && pageX <= offset.left + width &&
                      pageY >= offset.top && pageY <= offset.top + height) {
                  $(".recent-folder-link", this).triggerHandler("mouseenter");
              }
          });
      }
docs: Check the list of items to see if any of them are hovered, and if so trigger a mouseenter.
  Normally the mouseenter event handles this, but when a previous item is deleted and the next
  item moves up to be underneath the mouse, we don't get a mouseenter event for that item.
