fix: the date line is drawn in full too; no header line ellipsizes

With the subject and both address lines already drawn whole, the Date
follows and the ellipsis flag goes with it: every header line is bounded
only by its clip rect — the plate's content edge, or the HTML-view
buttons' left edge for a line in their band.
