Feature Request: on dragstart using custom image

[n1crack]

how can I use custom image when dragging like :

el.addEventListener('dragstart', function (e) {
  const img = image_element;
  e.dataTransfer.setDragImage(img, 0, 15);
  e.dataTransfer.effectAllowed = 'all';
  e.dataTransfer.dropEffect = 'copy';
  e.dataTransfer.setData('data', 'test');
});

the events provided are returning MouseEvent, not DragEvent
