Background Task Defer Request

gcDelayExample.js

function onDrag(event){
  if(!dragging){
    return
  }
  
  // Tell the browser you are doing important stuff
  // It will decide whether or not to delay background tasks for a small period of time
  // For example, not doing garbage collection if it isn't really critical.
  // It might also decided not to, if it NEEDS to GC, or paint, or anything.
  window.requestBackgroundTaskDefer();
  
  // Obvs use css transforms but you get the idea.
  someElement.top = event.pageY + 'px';
  someElement.left = event.pageX + 'px';
}

window.addEventListener('mousemove', onDrag);

I already miss the stupid version
