背景过滤器不适用于 Chrome 中的嵌套元素

我有一个div.outer和里面一个div.inner，都与position: absolute; and backdrop-filter: blur(8px);.

Safari（左）给出了想要的结果——两个 div 都模糊了它们后面的内容。

然而，Chrome（右）仅应用模糊div.outer:

我有一个解决方案：在里面添加另一个divdiv.outer和移动backdrop-filter: blur(8px);到那个新的div。

但是，我希望有一个不需要从第一个 jsbin 更改 DOM 的解决方案。另外，有人知道是什么原因造成的吗？是 Chrome 的错误吗？

PS：它适用于iOS的Chrome，但不适用于Android的Chrome，也不适用于Mac OS的Chrome

将背景过滤器放置在 css 伪元素上。这允许嵌套背景过滤器。您也可以使用z-index: -1;将背景放置在元素后面

div {
  height: 100px;
  width: 100px;
}
.wrapper {
  position: absolute;
}
.outer, .inner {
  position: relative;
}
.outer::before {
  content: '';
  position: absolute;
  width: 100%;
  height: 100%;
  -webkit-backdrop-filter: blur(8px);
  backdrop-filter: blur(8px);
}
.outer {
  background: rgba(255, 0, 0, .5);
}
.inner::before {
  content: '';
  position: absolute;
  width: 100%;
  height: 100%;
  -webkit-backdrop-filter: blur(8px);
  backdrop-filter: blur(8px);
  
}
.inner {
  background: rgba(0, 0, 255, .5);
  top: 50px;
  left: 50px;
}
main {
  position: relative;
}

<main>
  <div class="wrapper">
    <div class="outer">
      <div class="inner"></div>
    </div>
  </div>
