Custom Resources not removed using helm uninstall - v2.3.1

Hi All,

I've managed to install traefik v2.3.1 using helm (chart version: 9.5.1). However, when trying to uninstall it using the same chart I'm left with all the CRDs in place (everything else is removed).

Is that the right behavior to expect?

edit:
Also, please explain what is the correct way to remove these CRDs without messing the environment.

Thanks in advance!
