Uninstalling cert-manager-operator does not remove cert-manager controller,cainjector,webhook pods

After uninstalling the openshift-cert-manager-operator (v1.10.2) from OpenShift console using the standard "Uninstall Operator" option, the cert-manager operand continues to stay active on the cluster.

The 3 deployments and it's pods in the cert-manager namespace remain existent even after operator has been uninstalled. This also has a negative impact as Certificate, Issuer, etc. etc. cert-manager related objects on the cluster continue to be in a state where they are reconcile-able even after Cert Manager Operator for Red Hat OpenShift has been uninstalled.

openshift-cert-manager-operator-v1.10.2

Always

1.Install the operator from Console
2.Wait till installation succeeds and a few more minutes after for everything to be up and running
3.Uninstall the operator from the Console
4. $ oc get pods -n cert-manager
--- 3 cert-manager pods will remain ---
Same for the deployment:
$ oc get deploy -n cert-manager
cert-manager
cert-manager-cainjector
cert-manager-webhook

Operand pods continue to remain functional after operator uninstallation.

Operand pods/deployment should be cleaned up after uninstallation or some supported way for cleaning them up.
