Element is missing end tag.

Describe the bug

Why did I encounter Element is missing end tag? I can't understand this error

<!DOCTYPE html>
<html>
  <head lang="en">
    <meta charset="UTF-8" />
    <title></title>
    <style>
      /*申明字体*/
      @font-face {
        font-family: "iconfont";
        src: url("font/iconfont.eot"); /* IE9*/
        src: url("font/iconfont.eot?#iefix") format("embedded-opentype"), /* IE6-IE8 */
            url("font/iconfont.woff") format("woff"),
          /* chrome、firefox */ url("font/iconfont.ttf") format("truetype"), /* chrome、firefox、opera、Safari, Android, iOS 4.2+*/
            url("font/iconfont.svg#iconfont") format("svg"); /* iOS 4.1- */
      }

      p {
        width: 200px;
        border: 1px solid #000;
        line-height: 60px;
        font-size: 30px;
        margin: 100px auto;
        text-align: center;
        position: relative;
      }

      .icon::before {
        content: "\e628";
        font-family: iconfont;
        color: red;
      }

      span {
        position: relative;
      }
    </style>
  </head>
  <body>
    <p class="icon">扫码付款</p>
    <span class="icon">我是span</span>
    <div class="icon">divvvvvvvvvvv</div>
  </body>
</html>

If this is a markdown verification error, can we make Vitepress more compatible with this type of error, or can we have a switch to enable this function
