The key permission for the comments moderation is “if user can edit a post, to which a comment was sent”: edit_posts, edit_published_posts, edit_others_posts.
‘moderate_comments’ is not about that. More information is here.
I don’t have a solution, how to prevent editors or even authors from comments moderation.
