Hi @fariaNawrine!
You have found another usage of the wrong code but with the same root cause as in #20440. After refactoring, the zones object copy on series was shallow, not deep, what creates an issue.

I've prepared a workaround for your issue, if you want to use it in your project, simply copy-paste the IIFE function.
Live demo with a workaround: https://codepen.io/hubertkozik/pen/gOEeJdM
