Unless I'm misunderstanding, I don't think this should be changed. self.role is the role you are requiring in the endpoint, so this would mean even if the user u is not an editor, if your permission requires editor this would return true for any user in the group.

ah i see i misunderstood the self.role part. Sorry about that.
Will revert it
