Any additional comments?

This is intended for breaking large library into small files, instead of loading one giant file.

I think this is a bug. In the process of rendering the content of the custom element wrapped by defineAsyncComponent, if it is bound to an attribute, such as id, then its vnode will be used by the cloneVNode method Cloning, but the cloning of the ce attribute was omitted during cloning, resulting in being parsed into a normal component, and finally the event could not be triggered。
