Safari 嵌套 flex 问题

Question

嵌套的 flex 盒，同级为 flex-grow : 1 和 overflow-y : auto 在 Safari 中无法正常工作 [我的 build 13.1 (14609.1.20.111 .8)]。这在 Chrome 中再次很好用。附上这两个项目的屏幕截图以及最小可重现代码块。

如果我们给 flex-basis : [n]px 给第二个孩子一个固定的大小.. 它工作正常。但是我们不能总是期望给出它，因为第二项中的内容是动态的。在下面的代码块中，给出了一个最小的可重现用例。

.parent {
  flex-direction: column;
  display: flex;
  background-color: #CCC;
  padding: 8px;
  height: 150px;
  font-size: 16px;
}

.fixedChild {
  display: flex;
  padding: 10px;
  justify-content: space-between;
  flex-basis: auto;
}

.growingChild {
  overflow-y: auto;
  flex-grow: 1;
}

/*! CSS Used from: Embedded */
.fancyButton {
  background-color: transparent;
  border: 1px solid transparent;
  border-color: #0076D1;
  border-radius: 15px;
  color: #0076D1;
  height: 50px;
  justify-content: center;
  outline: none;
  padding: 0 8px;
}

<div class="parent">
  <div class="growingChild">
    Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.

    The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham.

Answer 1

这并没有解决潜在的不一致问题，而是将最后一个子项（flex item）设置为：

flex-shrink: 0;

似乎使 Safari 和 Chrome 的行为相同，其中 flex 容器占按钮的高度以及不断增长的 flex 项兄弟。不知道谁对谁错，但我觉得可能是 Safari ?？
