Chrome下滚动条的奇怪Z索引行为 [英] Strange z-index behavior with scrollbars under Chrome

问题描述

在固定"定位的元素上使用z-index CSS属性给我一个奇怪的行为，在Chrome下.

Using z-index CSS property on 'fixed' positioned elements gives me a strange behavior under Chrome.

当Firefox和Opera浏览器给我期待的结果时，Chrome似乎不尊重z-index属性，将滚动条显示在红色叠加层上方(请参见代码和Fiddle波纹管).

When Firefox and Opera browsers give me the awaited result, Chrome does not seem to respect the z-index property, displaying the scrollbar above the red overlay (see code and Fiddle bellow).

HTML:

<div class="left">
    <div class="placeholder"></div>
</div>
<div class="right"></div>
<div class="overlay"></div>

CSS:

.left {
    background-color: yellow;
    bottom: 0;
    left: 0;
    overflow: auto;
    position: fixed;
    top: 0;
    width: 35%;
    z-index: 10;
}

.right {
    background-color: orange;
    bottom: 0;
    position: fixed;
    right: 0;
    top: 0;
    width: 65%;
    z-index: 20;
}

.overlay {
    background-color: red;
    bottom: 20%;
    left: 25%;
    position: fixed;
    right: 25%;
    top: 20%;
    z-index: 40;
}

.placeholder {
    height: 3000px;
}
