Force full row rebuild when selection span changes

Force full row rebuild when selection span changes

planRowRefresh only considered VT dirty flags, so pointer-driven
selection changes (motion, click) never triggered row rebuilds and
the highlight was never painted.

Track the selection span before draining the pointer queue and force
.full rebuild mode when it changes.
