Hello,

Reproduction link

https://stackblitz.com/edit/react-7nox59?file=demo.js

Steps to reproduce

My stackblitz (demo.js file) already show a broken menu because PermissionComponent is returning null.

What is expected?

PermissionComponent should be able to return null and then the menu item wrapped should be ignored and hidden.
Important: The same code for a vertical mode of antd menu works

What is actually happening?

The menu crashed

I am forking the repo. and debugging it => in the little time i have each day it will take time :)
Thanks in advance for your help if you can solve it faster
