See https://w3c.github.io/pointerevents/#dfn-lostpointercapture: "This event MUST be fired prior to any subsequent events for the pointer after capture was released." This is not always the case; we fail the third subtest of the wpt test pointerevents/pointerevent_lostpointercapture_for_disconnected_node.html as a result.
