@SessionAttributes is not supported by webflux.
I am expecting same @MVC code work in both servlet or netty environment.
A very simple example (spring-boot, kotlin, thymeleaf):
This demo works as expected - increasing numbers displayed for each request in web brower - with webmvc,
but not working - the number is always 1 - with webflux.
There's no SessionStatus argument resolver in webflux too.
