在深度嵌套的 flex 容器中滚动 - 最小高度不起作用

Question

我有以下弹性布局。我需要在 div.stretchy 中发生溢出。我希望 div.stretchy 到达页面的边界，然后溢出它的内容。根据这个stackoverflow post，我尝试了很多min-height: 0和overflow: hidden的组合，但是div.stretchy不会缩小。

body {
  margin: 0;
}

.page-wrapper {
  display: flex;
  height: 100vh;
  width: 100vw;
  overflow: hidden;
}

.sidebar {
  background: blue;
  flex: 0 0 40px;
}

.main {
  background: green;
  display: flex;
  flex-direction: column;
  flex: 1;
  min-width: 0;
}

.topbar {
  display: flex;
  flex: 0 0 40px;
  background-color: red;
}

.content {
  display: flex;
  overflow: auto;
}

.row {
  display: flex;
}

.column {
  display: flex;
  flex-direction: column;
}

.grow {
  flex-grow: 1;
}

.card {
  height: 300px;
  border: solid 1px;
  min-width: 600px;
}

.card .row {
  justify-content: space-between;
}

.wrapper {
  padding: 16px;
  height: fit-content;
}

.stats {
  padding: 8px;
  background-color: pink;
}

.overflow-hidden {
  overflow: hidden;
}

.body .column {
  background-color: indigo;
}

.wide-content {
  background-color: yellow;
  height: 50px;
  width: 800px;
}

.block {
  flex: none;
  width: 300px;
  height: 200px;
  &:nth-of-type(odd) {
    background: darken(green, 10%);
  }
}

<div class="page-wrapper">
  <div class="sidebar">sidebar</div>
  <div class="main">
    <div class="topbar">topbar</div>
    <div class="content">
      <div class="wrapper">
        <div class="card column grow">
          <div class="stats row">
            <span>12345</span>
            <span>12345</span>
            <span>12345</span>
          </div>
          <div class="body row grow">
            <div class="column">
              <span>Dynamic Width Content</span>
            </div>
            <div class="stretchy column grow overflow-hidden">
              <div class="wide-content grow"></div>
            </div>
            <div class="column">
              <span>Dynamic Width Content</span>
            </div>
          </div>
        </div>
      </div>
    </div>
  </div>
</div>

这是一场艰苦的战斗。敌人狡猾、诡诈、无情。我说我们发起了一场大规模的地毯式轰炸活动，用最小尺寸覆盖整个区域。这应该可以解决 80% 的问题。然后我们派地面部队完成工作:-)
