Coalesced/predicted events in untrusted PointerEvents will retain original targets

Category: User input
Type: No developer-visible change
Status: Enabled by default (Chrome 130)
Intent stage: None

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.
