When these links are clicked, a wrong message appears about missing/moved comment.
This message is: Could not find the comment you're replying to on the page. It might have been deleted or moved to another page. Please reload the page and try again.
But this is not the case, comments are not moved/deleted. And if the page is reloaded nothing changes.
