I've created an example to demonstrate the issue:  
[https://github.com/kocsis1david/apm-route-bug](https://github.com/kocsis1david/apm-route-bug)

If you use the simple `Route`, the number will increase when switching between paths, see this [video](https://drive.google.com/file/d/1JvOa7GBbvYSvuYEJxqzI4v96OepnSmgJ/view). But if you replace `Route` to `ApmRoute`, the number will always be `1`. The `ApmRoute` is already imported so it's easy to replace to it in the example.

The cause of the problem seems to be that hooks lose their states when the route is changed, and `useState` will reset the `counter` to its default value.
