You can now pass a ref to a Node to keep a reference to it.

[x] No

[tk-fp]

Ran into a issue while testing, lets hold on the pr for now.

Cannot use forwardRef as it only ever references the first node loaded and does not change when selecting a new node.

Instead I am able to pass a ref to the node back on the onDragEnd event by setting the srcElement prop of the event to the node itself.

Suggested change

	const nodeRef = useRef<SVGRectElement>(null);
	const nodeRef = useRef<SVGRectElement | null>(null);

Was the srcElement there before or is this a new prop?

[tk-fp]

It's a new prop.

[tk-fp]

It is a prop on the actual pointer event on event.event but this is one level up on the top level event. So you are able to see event.srcElement: the element that the onDragEnd event occurred from and event.event.srcElement: element the pointerup event happened on, same as event.event.target.
