CSS滚动捕捉不适用于CSS Grid

Question

在Flexbox中使用CSS滚动捕捉时，捕捉效果很好：

* {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
}
.slider {
  font-family: sans-serif;
  scroll-snap-type: mandatory;
  scroll-snap-points-y: repeat(100vw);
  scroll-snap-type: x mandatory;
  display: flex;
  overflow-x: scroll;
}
section {
  border-right: 1px solid white;
  padding: 1rem;
  min-width: 100vw;
  height: 100vh;
  scroll-snap-align: start;
  text-align: center;
  position: relative;
}
h1 {
  position: absolute;
  top: 50%;
  transform: translateY(-50%);
  text-align: center;
  color: red;
  width: 100%;
  left: 0;
  font-size: calc(1rem + 3vw);
}

<div class="slider">
  <section>
    <h1>Section One</h1>
  </section>
  <section>
    <h1>Section Two</h1>
  </section>
  <section>
    <h1>Section Three</h1>
  </section>
  <section>
    <h1>Section Four</h1>
  </section>
  <section>
    <h1>Section Five</h1>
  </section>
</div>

但是，当尝试将CS​​S Grid与CSS Snap一起使用时，它似乎不起作用：

* {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
}
.slider {
  font-family: sans-serif;
  scroll-snap-type: mandatory;
  scroll-snap-points-y: repeat(100vw);
  scroll-snap-type: x mandatory;
  display: grid;
  grid-gap: 10px;
  grid-template-columns: repeat(auto-fill, 100vw);
  overflow-x: scroll;
  width: 600vw;
}
section {
  border-right: 1px solid white;
  padding: 1rem;
  min-width: 100vw;
  height: 100vh;
  scroll-snap-align: start;
  text-align: center;
  position: relative;
}
h1 {
  position: absolute;
  top: 50%;
  transform: translateY(-50%);
  text-align: center;
  color: red;
  width: 100%;
  left: 0;
  font-size: calc(1rem + 3vw);
}

<div class="slider">
  <section>
    <h1>Section One</h1>
  </section>
  <section>
    <h1>Section Two</h1>
  </section>
  <section>
    <h1>Section Three</h1>
  </section>
  <section>
    <h1>Section Four</h1>
  </section>
  <section>
    <h1>Section Five</h1>
  </section>
</div>

此行为的原因是什么，有没有办法使CSS Grid与CSS Snap一起使用？
