Research direction
Investigate the outline tree component and its undo event handling. Check the undo stack synchronization between canvas and outline tree. Look for event listeners or state management that updates the tree after undo. The issue reports that after undo, canvas updates but outline tree does not. Find the relevant files (likely in packages/outline tree or similar) and ensure the undo action triggers a re render or state update in the outline tree.
