regenerateTreeIds shallow-copied each node's data, leaving data.props (and data.custom) as the same object reference between the original node and its duplicate/pasted copy. Craft.js's setProp mutates data.props in place, so editing the duplicate's props silently mutated the original too. Deep-clone data via structuredClone before applying id remaps so no mutable sub-object is shared between original and regenerated nodes.
