Tree popup: act on the component as it is now, so tree delete is undoable on a device

Right-clicking a tree row selects it, and on a device that reopens the
sheet and rebuilds the DOM after the popup captured the row's element.
Delete then ran on a stale element: the device delete went through but
no undo step was recorded. Popup actions now look the component up by
id when they run.
