动画 SVG 边框图像不遵循边框半径

Question

我正在尝试通过使用带有边框图像的 SVG 来制作动画边框半径，并用边框半径将其舍入。我有

overflow: hidden;

但边界似乎不受此属性的影响。我将在下面给出当前代码以及 JSFiddle 中边框样式的示例。如有任何帮助，我们将不胜感激！

    margin: 0 auto;
    height: 80vh;
    font-size: 3vw;
    overflow: hidden;
    border: 5px solid;
    border-image: url(../images/borderAnimation.svg) 5 stretch;
    border-radius: 15px;
    background-color: rgb(70, 70, 70);

我知道这是一种作弊，但如果你可以有嵌套元素，那么父元素可以有背景，而子元素可以用颜色遮盖背景：

div.wrapper {
  width: 300px;
  height: 200px;
  border-radius: 10px;
  padding: 5px;
  background-image: url('data:image/svg+xml;base64,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');
  display: flex;
  align-items: center;
  justify-content: center;
}

div.wrapper>div {
  width: 100%;
  height: 100%;
  border-radius: 5px;
  box-sizing: border-box;
  background: white;
}

<div class="wrapper">
  <div></div>
</div>
