相对定位父级的绝对定位的psuedo元素的overflow设置为overflow：hidden

我正在通过CSS（jolly roger）制作一个戴着帽子的骷髅，可以在这个Codepen中找到。

在帽子部分，其下边缘必须从父div溢出，而帽子中的条纹必须具有overflow:hidden。
您可以在firefox和chrome中打开codepen链接以发现差异。

虽然我的代码在Firefox中可以正常工作，但在chrome中似乎无法正常工作。我已经尝试了许多解决方案，这些解决方案说明了如何将绝对项目放置在带有Overflow：hidden的相对父级中，但是这些似乎都不起作用。也许我错过了一些重要的事情。

的HTML

<div class="skull">
  <div class="skull__face skull__face--animate">
    <div class="skull__upper">
      <div class="skull__hat"></div>
      <div class="skull__nose"></div>
    </div>
    <div class="skull__lower">
      <div class="skull__jaw"></div>
    </div>
  </div>
  <div class="skull__bone skull__bone--left"></div>
  <div class="skull__bone skull__bone--right"></div>
</div>
