我有一个问题，我的头下拉不工作在Safari浏览器;它在Chrome浏览器中工作正常，但当我打开Safari时出现问题：我不能点击我的下拉菜单打开另一个下拉菜单。它是无法点击的，你有过这种问题吗？我使用<a>标签，也尝试了<span>，但没有改变。
下面是我的代码：

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

header {
  top: 0;
  left: 0;
  right: 0;
  background: #ffffff;
  padding: 0px 7%;
  display: flex;
  align-items: center;
  justify-content: space-between;
  z-index: 10000;
  .navbar ul {
    list-style: none;
  }
  .navbar ul li {
    position: relative;
    float: left;
  }
  .navbar ul li a,
  span {
    padding: 20px;
    color: #111d5e !important;
    font-weight: 600;
    text-decoration: none;
    display: block;
  }
  .navbar ul li a:after {
    background: none repeat scroll 0 0 transparent;
    bottom: 0;
    content: "";
    display: block;
    height: 2px;
    box-shadow: inset 3000px 0 0 0 #eed484;
    transition: width 0.3s ease 0s, left 0.3s ease 0s;
    width: 0;
  }
  .navbar ul li a:hover:after {
    width: 100%;
    left: 0;
  }
  .navbar ul li span:after {
    background: none repeat scroll 0 0 transparent;
    bottom: 0;
    content: "";

    width: 0;
  }
  .navbar ul li span:hover:after {
    width: 100%;
    left: 0;
  }
  .navbar ul li ul li span,
  a {
    width: 100%;

  }
  .navbar ul li .language {
