我希望圆形路径（遮罩）填充0到100％的长度并不断重复。我正在尝试在SVG文件中完成所有操作，以使其更整洁。
我一直在学习具有以下简化代码的教程（运行摘要）：
<svg viewBox="0 0 340 333">
<path class="path" fill="white" stroke="black" stroke-width="4" d="M66.039,133.545c0,0-21-57,18-67s49-4,65,8
s30,41,53,27s66,4,58,32s-5,44,18,57s22,46,45s-54-40-68-16s-40,88-83,48s11-61-11-80s-79-7-70-41
C46.039,146.545,53.039,128.545,66.039,133.545z" />
<style>
.path {
stroke-dasharray: 1000;
stroke-dashoffset: 1000;
animation: dash 5s linear forwards infinite;
}
@keyframes dash {
from {
stroke-dashoffset: 1000;
}
to {
stroke-dashoffset: 0;
}
}
</style>
</svg>
我的svg有一个遮罩，我正在使用相同的技术来遮罩。因此，它应该从箭头的起点到末端从0到100的周长露出，然后重复进行..但是我无法笔触从0长度开始。.我下面有一个圆圈，在做相同的动画，但它以长划线而不是0长度开始。
我在圈子/路径代码中缺少什么吗？我怎样才能像上面的例子一样行动？我的代码段：

我还已经将圆转换为路径，认为这会有所帮助（因为本教程具有路径），但是它在做相同的事情：
