Pure render for tree data, fixes React Canary useMemo/useState StrictMode (#5835) * Pure render for useTreeData * adjust some more calls * fix accumulation of build trees * better readability * fix typo * fix remaining broken tests * revert canary testing changes * fix lint * updating naming and making things a bit easier to read * make sure a new map is always generated in insert for purity * make useTreeData always use and return a new Map this avoids the case where we may inadvertantly modify the previous map directly which could be problematic in a double render * guard against empy array in remove --------- Co-authored-by: Daniel Lu <dl1644@gmail.com>
