fix: list rows run across the bottom roll to the window edge

5fa4e68 stopped the row clip at the face edge, where the bottom roll
begins, so text still cut off about a bevel width above the plate's
visible bottom. The clip now runs to the window edge. The compositor
already cuts the window to its rounded silhouette, so the corners need
no clip of their own. Scrolled to the end, the last row still rests the
plate inset clear of the edge, the same as at the other edges.
