为什么我不能在Chrome的CSS翻页卡上单击链接的左侧？

Question

尝试单击此挂卡背面的链接的左侧”在Chrome中不起作用。但是，当我将鼠标悬停在链接的right一侧时，我看到了指针光标并能够与之交互：

.card {
  -webkit-perspective: 1000px;
  perspective: 1000px;
  display: inline-block;
}

.card .card-inner {
  position: relative;
  -webkit-transition: -webkit-transform 0.6s;
  transition: -webkit-transform 0.6s;
  -o-transition: transform 0.6s;
  transition: transform 0.6s;
  transition: transform 0.6s, -webkit-transform 0.6s;
  -webkit-transform-style: preserve-3d;
  transform-style: preserve-3d;
  will-change: transform;
}

.card .card-inner .card-face {
  position: absolute;
  top: 0;
  left: 0;
  height: 100%;
  width: 100%;
  -webkit-backface-visibility: hidden;
  backface-visibility: hidden;
}

.card .card-inner .card-face.card-back {
  -webkit-transform: rotateY( 180deg);
  transform: rotateY( 180deg);
}

.card .card-inner .card-face .card-face-inner .card-face-content {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  -webkit-backface-visibility: hidden;
  backface-visibility: hidden;
  display: -webkit-box;
  display: -ms-flexbox;
  display: flex;
  -webkit-box-align: center;
  -ms-flex-align: center;
  align-items: center;
  -webkit-box-pack: center;
  -ms-flex-pack: center;
  justify-content: center;
  font-family: Arial, sans-serif;
  font-size: 22px;
}

.card:hover .card-inner {
  -webkit-transform: rotateY( 180deg);
  transform: rotateY( 180deg);
}

.card .card-back {
  background: steelblue;
}

<div class="card">
  <div class="card-inner">
    <img src="https://via.placeholder.com/400x500?text=%20" alt="" />

    <div class="card-face card-front">
      <div class="card-face-inner">
        <div class="card-face-content">
          Front
        </div>
      </div>
    </div>

    <div class="card-face card-back">
      <div class="card-face-inner">
        <div class="card-face-content">
          <a href="#foo">Back</a>
        </div>
      </div>
    </div>
  </div>
</div>

如何解决此问题，以便整个链接都可单击？我猜想这与backface-visibility有关。我遇到了this StackOverflow answer，但是我认为该解决方案已经在此处实现，包括以下行：

.card .card-inner {
    ...
    -webkit-transform-style: preserve-3d;
    transform-style: preserve-3d;
}

我不知道原因，但这很可能是一个错误，因为它可以按预期在Firefox上运行。将pointer-events: none;添加到.card-inner并将pointer-events: auto添加到.card-face是可行的，只有上帝知道原因。

原因是由于Chrome中的小精度误差，180度并非完全是半圈。

并且元素的左侧是under的正面（即使您看不到它，它仍然存在）。

将元素沿Z方向升高，仅一个像素，它就可以工作（现在完全在另一边）：
