在谷歌浏览器中，element.scrollIntoView() with behavior: 'smooth'不能同时在多个容器上工作。一旦在一个容器上触发平滑滚动，第二个容器就会停止滚动。在Firefox中，这个问题不存在；两个容器可以同时滚动。
我的解决方法是使用behavior: 'instant'，但我喜欢用behavior: 'smooth'为了更好的用户体验。

<p>
In Google Chrome element.scrollIntoView() with behavior 'smooth' doesn't work, if scrolling more containers at the same time.
Shwon in case 'All Smooth (200ms sequence)' the container stopps scrolling.

<br> In Firefox all works.
