When reviewing reopen votes triggered by an edit, the Revision tab should show the edit summary:
Often, there's valuable context that the edit summary explains which a reviewer may not understand if unfamiliar with the particulars of the question.
As an example, twice I've edited questions (not mine) that were closed as unclear, by clarifying the question and further explaining in the summary that the question was actually clear to those familiar with the obscure tag. In the end I had to ask moderators to reopen because the reviewers never saw my summary! In both cases, the question was subsequently answered and accepted.
