爲什麼純Css監聽點擊事件並觸發滾動事件？

我有以下片段。我沒有編寫任何腳本，它是純Css，但是當點擊標題時會觸發一些奇怪的事件。如果您單擊向下滾動並單擊標題，div容器將自動向上滾動。這是我想禁用它的不需要的事件。有人可以解釋爲什麼嗎？以及如何禁用它？爲什麼純Css監聽點擊事件並觸發滾動事件？

它不觸發點擊，當它被點擊標題和鼠標移動，造成滾動。剛上header級傷殘pointer-events： https://jsfiddle.net/8LcLvh93/1/

.header { 
    broder: solid 1px black; 
    position: absolute; 
    color: black; 
    top: 10px; 
    pointer-events: none; 
}

快到了，是否有可能禁用指針事件對於滾動只是因爲我想以後我的JavaScript中使用這個元素 – TSR
