Vue.js 中 v-html 会导致哪些问题?

let template = require('vue-template-compiler');
let r = template.compile(`<div v-html="'<span>hello</span>'"></div>`)
// with(this){return _c('div',{domProps:{"innerHTML":_s('<span>hello</span>')}})}
console.log(r.render);
// _c 定义在core/instance/render.js
// _s 定义在core/instance/render-helpers/index,js
if (key === 'textContent' || key === 'innerHTML') {
      if (vnode.children) vnode.children.length = 0
      if (cur === oldProps[key]) continue
      // #6601 work around Chrome version <= 55 bug where single textNode
      // replaced by innerHTML/textContent retains its parentNode property
      if (elm.childNodes.length === 1) {
        elm.removeChild(elm.childNodes[0])
      }
}
