Flex-box项目无法在chrome上正确重新呈现

Question

当以编程方式更改尺寸或弹性框项目的位置属性时，我遇到了不同的浏览器行为。布局未在Chrome上恢复其原始状态。

在此pen中，当用户点击图片时，我将项目位置更改为绝对并修改其宽度和高度（实际上它可能是影响布局的任何内容，例如填充）。当用户再次单击时，我回滚了更改，因此我希望布局相应地重置。

一个js的解决方法是通过快速地将项目填充来回改变1px来强制布局重新渲染，但我想知道：

为什么会发生这种情况，是否只有css解决方法？

铬

当用户再次单击并重置弹性项目样式时，不再考虑弹性基础并且布局中断。

火狐

当用户再次单击并重置弹性项目样式时，将正确呈现所有项目。

该问题看起来异常，但修复相当简单。将min-height: 0添加到.ig-item。

可能问题似乎是浏览器如何表明默认情况下flex项目的min-height属性为 auto 。

见下面的演示：

new Vue({
  el: '#app',

  data() {
    return {
      activeImageIndex: null,
      images: [{
          url: 'https://unsplash.it/600',
          style: {
            flexBasis: '50%'
          }
        },
        {
          url: 'https://unsplash.it/600',
          style: {
            flexBasis: '50%'
          }
        },
        {
          url: 'https://unsplash.it/600',
          style: {
            flexBasis: '30%'
          }
        },
        {
          url: 'https://unsplash.it/600',
          style: {
            flexBasis: '30%'
          }
        },
        {
          url: 'https://unsplash.it/600',
          style: {
            flexBasis: '30%'

    }
