CSS Animate SVG笔划在最后一帧停止

在上面的代码中有一个SVG,笔画动画进入视图,但最后它只是消失了.

有没有办法在加载后将其保持在视图中？

.path {
  stroke-dasharray: 1000;
  stroke-dashoffset: 1000;
  animation: dash 5s linear alternate;
}

@keyframes dash {
  from {
    stroke-dashoffset: 1000;
  }
  to {
    stroke-dashoffset: 0;
  }
}

animation-fill-mode: forwards; // Stay on the last frame
    animation-iteration-count: 1;// Run only once

Css将是：

.path {
  stroke-dasharray: 1000;
  stroke-dashoffset: 1000;
  animation: dash 5s linear alternate;
animation-fill-mode: forwards; // Stay on the last frame
    animation-iteration-count: 1;
}

Codepen是Here,它的工作正常.
