Waiting for someone to comment on this. My personal feeling is it doesn't matter since they are both phrasing content in whichever order. code cannot have pre as children because pre is not phrasing content, so pre > code is the only correct order. Also the point of that note is not what wraps what anyway—it's that you need to have a pre tag in order to display code blocks. sup and a doesn't constitute a special combination unlike pre + code, so I personally don't see the point in documenting this. But I'm not HTML expert either.
