Summary

For untrusted (i.e. JS constructed) PointerEvents, the events returned by PointerEvent.getCoalescedEvents() and PointerEvent.getPredictedEvents() will maintain their original targets and offsetX/Y coordinates, instead of behaving like trusted events where these fields are affected by the parent (container) event.
