Reviewed by Simon Fraser.
The preserving of a particular snap target was intended to follow this line
of the spec: "If multiple boxes were snapped before and their snap positions
no longer coincide, then if one of them is focused or targeted, the scroll
container must re-snap to that one and otherwise which one to re-snap to is
UA-defined". Since it is specified that this is for the case of mulitple boxes
being snapped, change the logic so that we only preserve a target if we are
snapped to multiple boxes.
