EBS volume type standard not working on Kubernetes

The EBS volume type standard seems not working as a storage class on Kubernetes.

Reproduce the issue

Adding the following storage class:

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: standard
  labels:
    k8s-addon: storage-aws.addons.k8s.io
provisioner: kubernetes.io/aws-ebs
parameters:
  type: standard
reclaimPolicy: Delete

by the following commands:

kubectl apply -f config/storage-class-standard.yaml
kubectl patch storageclass gp2 -p '{"metadata": {"annotations":{"storageclass.beta.kubernetes.io/is-default-class":null}}}'
kubectl patch storageclass standard -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
