Doesn't detect Docker Rootless

I'm unable to reproduce this. I'm running Docker in rootless mode. It will check for a .dockerenv file in the root and mine is there. It does a second check for the string "docker" in /proc/self/cgroup and that is there too.

How did you install docker rootless? Is there anything special about your configuration?

$ docker info | grep rootless-mode
WARNING: Running in rootless-mode without cgroups. To enable cgroups in rootless-mode, you need to boot the system in cgroup v2 mode.

$ docker run -it is_docker bash
