Flexbox、flex-direction：列、图像和 IE11 错误。这可以解决吗？

Question

我有一个包含<ul> 的display: flex 水平。每个<li> 的宽度为 25%，display: flex 的高度也相同。

每个<li> 都包含一个display: flex 列的锚点，以正确对齐其中的元素，包括主图像容器和图像。在包括 IE10 在内的所有浏览器中，这都很好，没有问题。然而，在 IE11 中，问题就从这里开始了。

IE11 将图像容器高度计算为源图像的实际高度，而不是渲染时图像的高度。这最终会渲染<li> 比它应该的高得多。

布局在每个自尊的浏览器中的外观：

布局在 IE11 中的外观：

我知道这可以通过明确定义图像高度来解决，但我不想这样做。我也可以用 JS 来解决它，但同样，我不应该这样做。我错过了什么吗，因为它似乎没有在Flexbugs 上列出。

这似乎可以通过在.promotions-list__item__header 上设置flex: 0 0 auto 来解决。

* {
  box-sizing: border-box;
}

img {
  display: block;
  width: 100%;
}

.promotions-list {
  background-color: #eaeaea;
  display: -webkit-box;
  display: -webkit-flex;
  display: -ms-flexbox;
  display: flex;
  -webkit-flex-wrap: wrap;
  -ms-flex-wrap: wrap;
  flex-wrap: wrap;
  padding: .5rem 1rem;
  width: 960px;
}
.promotions-list__item {
  display: -webkit-box;
  display: -webkit-flex;
  display: -ms-flexbox;
  display: flex;
  padding: 1rem;
  width: 25%;
}
.promotions-list__link {
  background-color: white;
  display: -webkit-box;
  display: -webkit-flex;
  display: -ms-flexbox;
  display: flex;
  -webkit-box-flex: 1;
  -webkit-flex: 1 1 auto;
  -ms-flex: 1 1 auto;
  flex: 1 1 auto;
  -webkit-box-orient: vertical;
  -webkit-box-direction: normal;
  -webkit-flex-direction: column;
  -ms-flex-direction: column;
  flex-direction: column;
  overflow: hidden;
  padding: 1em;
  position: relative;
  width: 100%;
}
.promotions-list .image-container {
  display: block;
  height: auto;
}
.promotions-list .image-container img {
  display: block;
  margin: 0 auto;
  max-width: 40%;
}

/* Added */
.promotions-list__item__header {
  flex: 0 0 auto;
}

<ul class="promotions-list">
    <li class="promotions-list__item has-image">
