Safari上的jQuery手风琴问题

Question

我有一个非常简单的使用jQuery slideUp / slideDown构建的手风琴。它在Chrome / Firefox中运行良好，但是在Safari中出现了一个奇怪的Flash问题。它主要发生在您从手风琴的底部开始并单击向上的项目时。

具体来说，如果打开并关闭每个选项卡似乎没有问题，但是当“许可”打开时，单击它们并向上看，您会看到闪光灯。

我尝试了许多不同的解决方案，似乎无法解决仅Safari的问题。我该如何解决？

// accordian functionality
$('.contact-item').on('click', function() {

  // Check if this is already active
  if ($(this).hasClass('active')) {
    // Slide up panel, remove class
    $(this).find('.contact-info').slideUp(250);
    $(this).removeClass('active');

  } else {
    // Slide up any open panel
    // Remove active class from any open service panel
    $('.contact-info').slideUp(250);
    $('.contact-item').removeClass('active');

    // Open accordian panel
    // Add class to active item
    $(this).find('.contact-info').slideDown(250);
    $(this).addClass('active');
  }

});
