Plan step 32, found by the Browser suite. Content padding (16dp by default
since containment.md C-12) shrinks every keyline near the ends, so large
items resting at the start or the end carry a small inset. Bring-into-view
took any inset over half a pixel for "not fully open", so focusing or
pressing a large item at rest scrolled the row to it. The focal keyline's
own inset at the current scroll is the threshold now. The press test also
checks that focusing and pressing an open item moves nothing.
