1. Create a role with policies listed below:
2. Create a user with role from step 1
3. Log in as a new user
4. Go to dashboard and click on edit button next to a content item
It seems like nothing has happened. Only console shows 403 (forbidden). It is ok, because there is no Versionread policy. But user can be a little confused without any information.
Maybe user could be informed that it is forbidden or a policy is missing.
