Steps to reproduce

就是那个单文件递归菜单click和select方法取不到title

What is expected?

希望点击菜单能得到该item的title值

What is actually happening?

单文件递归的时候click事件title取不到

事件名称	说明	回调参数
click	点击 MenuItem 调用此函数	function({ item, key, keyPath })
deselect	取消选中时调用，仅在 multiple 生效	function({ item, key, selectedKeys })
openChange	SubMenu 展开/关闭的回调	function(openKeys: string[])
select	被选中时调用	function({ item, key, selectedKeys })

文档说的 item 是 VueComponent Menu.Item 这个组件，并不是你的当前数组 item

那种单文件递归树生成的菜单如何点击获取数据呢，您能给点思路吗，我看它文档说使用单文件方式递归生成菜单，因组件内部会动态更改a-sub-menu的属性，如果拆分成单文件，无法将属性挂载到a-sub-menu上，需要自行声明属性并挂载。
