https://stackblitz.com/edit/react-ucebku-vmycow?file=app%2Fmain.jsx from the comments in this thread: https://www.telerik.com/forums/column-menu-doesn-t-work-in-custom-headers
The actual column menu for the "test" column (utilizing a custom headerCell) doesn't work.
Additionally, and this may be because I'm behind by a few versions, React doesn't like the `props={....props}` on `line 23`. However, despite it not working on my end locally, the demo is working with this but still not working overall.
