Unvisible unread comments if context not adjusted

Crucible review, viewing modified file with '3 lines' view context. If other reviewer adds a comment that is not visible in my context (e.g. 10 lines away from the nearest change), I get information that 1 comment is left unread, but no visual clue as to where the comment is. This is very confusing to users not very familiar with FE/CRU. I guess there should at the very least be some kind of warning that some comments are hidden in the current viewing context. Also, possibly the 'next/previous' comment navigation should ask me if I want to see the hidden comment. Screenshots attached (I saw only two comments, but the file tree on the left side was telling me there are three in the file and one is unread).
