I'd like to know if mutating JSON is advisable.

I ask because I've implemented a feature to copy and paste fields from other JSON objects. However, I always generate new IDs and assign them to both the parents and nodes. However, when I'm dragging a field from within a pasted group, it duplicates the node. Essentially, it doesn't remove the node from the nodes.

This feature worked in my scenario when there are no nodes within an imported group, where I can drag the nodes to any position, but when it's a node within a pasted group, it doesn't remove it from the nodes.
