Previously, narrowing would only work from recipient rows, not other message table rows (e.g. summary rows). This led to the trap that you could add a narrows_by_recipient class to an element, expect that narrowing would work, but the actual handler would break or silently fail if it weren't part of a recipient row. Now the click handler looks for the closest table row (tr). It's encapsulated in rows.get_closest_row(), so if we go to a non-table-based design, it should be easy to address in one place.
