Potential bug in useTreeState

[airtable-JayRansijn]

I am trying to use useTreeState from https://react-spectrum.adobe.com/react-stately/useTreeData.html and finding that tree.move() doesn’t always seem to re-render, and it seems the parentKey is incorrect sometimes.

CodeSandbox: https://codesandbox.io/s/treeview-for-issue-u73ne?file=/src/App.tsx
Example: https://u73ne.csb.app/
