On a phone or a narrow list, rows are two lines, and labels went on a third
line of their own. A row is a fixed height at each density, and that third
line fit it only at Comfortable: at Cozy, the default, the labels were cut
off at the bottom, and at Compact they sat outside the row.
They now sit on the sender's line, after the name, which has room to spare,
so the row's height is unchanged at every density. When the line runs short
the name gives way first, then each label truncates; the date stays.
