The previous attempt clamped the scrolling panes, and the panel still
slid. It was not the panes: overflow:hidden forbids the GESTURE, not the
engine, which keeps the right to move a box so the newly focused field
comes into view - and the rail's off-screen views, parked at
translateX(100%), leave it room to the right. Confirmed by measurement:
the CSS was in the shipped library and the behaviour was unchanged.
Caught in the capture phase now, whichever box moves and whatever moves
it. No view here has content to the right, except the folder strip.
