There is a case when a comment is opened by ReaderCommentsViewController on top of CommentDetailViewController.

This behavior was developed in the 1st phase where we redirect the user directly to Reader Comments screen if they don't permission to moderate the comment.

Also based on the View Debugger screenshot you shared, the Reader Comments screen is a child of NotificafionCommentDetailViewController, not CommentDetailViewController, which are 2 different view controllers.

As for old header design in the Reader Comments, I intentionally avoided redesigning it because I think it's out of scope of this phase. 🤔

Yeah, totally understand it, but the screen looks like a notification detail and does even have navigation buttons on the toolbar. That's why it looks confusing and not organically within the brand-new design system. 🤔
