PointerMoveEvent is not called when dragging the cursor over a UI Document

By design, during pointer capture as is the case with Button elements, neither Pointer events or Mouse events should be propagated to targets other than the capturing element. We fixed the behavior of mouse events to match that of pointer events, which is not what the bug description suggests but is what should really be happening (according to the design).
