https://stackblitz.com/run?file=src%2FApp.tsx,src%2FTreeView.tsx&showSidebar=0

🧐 Expected behavior

If no nodes are expanded nothing should happen. If any nodes are expanded all should be collapsed.

🧭 Possible Solution

Looks like the error is thrown here:

const expandedValue = Array.from(context.get("expandedValue"))
