Comment utiliser "overflow:hidden" sur "html" pour déplacer la zone de défilement vers le corps du texte

Question

Je viens de tomber sur l'utilisation de overflow:hidden 在 html et cela me semble illogique :

* {
  all: unset;
  display: revert;
}
html {
  height: 100vh;
  overflow: hidden;
  background: black;
}
body {
  height: 50vh;
  font-size: 5rem;
  background: white;
  scroll-snap-type: y mandatory;
  scroll-behavior: smooth;
  overflow-y: scroll;
}

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Il s'agit de déplacer la zone de défilement de l'élément html 移动到 body ，但我不明白为什么这个例子只适用于 overflow:hidden？ body的高度已经只有50vh，那么html pour qu'elle ne déborde pas, n'est-ce pas ?
