想问下以下这段代码为何bool为true的时候，没有结束函数调用？

想了很久，但是还是没有相同，copy了一个在线地址，麻烦各位大佬帮忙看看项目地址：https://codesandbox.io/s/serverless-butterfly-yzy4r2?file=/sr...

const getAdminIcon = (nodeList) => {
   console.log('nodeList', nodeList)

   let iconNode = null
   for (let i = 0; i < nodeList.length; i++) {
      let item = nodeList[i]
      console.log('item', item)
      let bool = item.classList && item.classList.contains('mdi-alpha-a-circle')
      console.log('bool', bool)
      if (bool) {
         iconNode = item
         break
      }
      if (item.childNodes.length === 0) {
         continue
      }
      iconNode = getAdminIcon(item.childNodes)
   }
   return iconNode
}
