Fix spacing of text fields in the review dialog.
Review Request #8500 — Created Oct. 27, 2016 and submitted
This change fixes the margin/padding of the inline editor fields in the review
dialog so that they don't jump when opening or closing the editors.
Created some comments, a header, and a footer, and opened/closed editors a
bunch.
