Describe the enhancement and the motivation for it.
I had a review with multiple reviewers and had been collapsing reviews after I finished addressing them. After publishing a reply to a review, ReviewBoard discarded the collapse state and all reviews showed up as expanded. When publishing a reply to a review, it should only publish the review you are working on and not change other state (e.g., which reviews are expanded/collapsed).
