I am trying to give service account permissions to run kubectl apply -f somerole.yaml on an existing role.

I created a service account with the following permissions:

cat > ~/tmp/Role.yaml <<EOF 
kind: Role
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata: 
  namespace: default
  name: my-role6
rules: 
- apiGroups: ["*"]
  resources: ["roles"]
  verbs: ["replace", "patch", "get", "list", "create"] 
EOF

kubectl create -f ~/tmp/Role.yaml  

All the background permissions (RoleBinding, context) seems to be good because if I add pods in the resources field I can use:
kubectl get pods --context=myservice6-context

When I run:

kubectl apply -f malrole.yaml --context=$CONTEXT_NAME

I received:

Error from server (Forbidden): error when creating "malrole.yaml": roles.rbac.authorization.k8s.io "testrole" is forbidden: attempt to grant extra privileges: [PolicyRule{Resources:["pods"], APIGroups:["*"], Verbs:["get"]}] user=&{system:serviceaccount:default:myservice6 5cdb719b-828b-11e8-993e-02420d415928 [system:serviceaccounts system:serviceaccounts:default system:authenticated] map[]} ownerrules=[PolicyRule{Resources:["selfsubjectaccessreviews"], APIGroups:["authorization.k8s.io"], Verbs:["create"]} PolicyRule{NonResourceURLs:["/api" "/api/*" "/apis" "/apis/*" "/healthz" "/swagger-2.0.0.pb-v1" "/swagger.json" "/swaggerapi" "/swaggerapi/*""/version"], Verbs:["get"]} PolicyRule{Resources:["roles"], APIGroups:["*"], Verbs:["replace" "patch" "get" "list" "create"]}] ruleResolutionErrors=[]

More readable version:

malrole.yaml (the file I tried to apply):

kind: Role
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
  namespace: default
  name: testrole
rules:
- apiGroups: ["*"]
  resources: ["pods"]
  verbs: ["get"]

It writes:

An attemp to grant extra privileges...

Which is taken from this line in the code:
https://github.com/kubernetes/kubernetes/blob/4d9873556201f2766ccf6161f7beac5f76b8fd60/pkg/registry/rbac/validation/rule.go#L52

Not sure why.

According to the documentation:

ConfirmNoEscalation determines if the roles for a given user in a given namespace encompass the provided role.

But I tried also give myself more permissions (see in the edit) and I still received this error.

EDIT:
even when I change the permissions to

kind: Role
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata: 
  namespace: default
  name: my-role6
rules: 
- apiGroups: ["*"]
  resources: ["roles"]
  verbs: ["*"]
