target.onlostpointercapture = functionRef;

functionRef is a function name or a function expression. The function receives a PointerEvent object as its sole argument.

function overHandler(event) {
  // Determine the target event's lostpointercapture handler
  let lostCaptureHandler = event.target.onlostpointercapture;
}

function init() {
  let el = document.getElementById('target');
  el.onlostpointercapture = overHandler;
}
