具有隐藏溢出（滚动）的弹性布局中的绝对定位按钮

Question

我正在尝试实现一个 Flex-layout 我已经实现的隐藏滚动条。但现在我还需要一个 absolute/fixed 按钮，但我没能让它工作。

没有隐藏的滚动条它工作：

但是当我隐藏滚动条时，按钮会粘在顶部，这是不受欢迎的。

<style>
    .root {
        background-color: #fff;
        display: flex;
        height:100%;
    }

    .pane {
        flex-grow: 1;
        flex-shrink: 1;
        display: flex;
        overflow-x: hidden;
        overflow-y: visible;
        -ms-overflow-style: none;
        height: 100%;
        width: 400px;
    }

    .pane::-webkit-scrollbar {
        display: none
    }

    div.pos {
        position: absolute;
        right: 0px;
        width: 32px;
        height: 32px;
        background-color: #01689B;
        color: #fff;
    }
</style>
<div class="root">
    <div class="pane">
        <div class="pos">x</div>
        <div style="height: 2000px">
            Lorem ipsum dolor sit amet, etc etc
            <br/> Lorem ipsum dolor sit amet, etc etc
            <br/> Lorem ipsum dolor sit amet, etc etc
            <br/> Lorem ipsum dolor sit amet, etc etc
            <br/> The button should stick to the right of the text and scroll width the text;
        </div>
    </div>
</div>

问题很简单，绝对定位元素与滚动元素无关。

给它 position: relative 它会的。
