研究方向
Investigate the focus management logic in MultiSelect2 component, likely located in packages/select/src/components/. Compare with the Select2 implementation to identify where focus gets reset to the first focusable element. Use browser DevTools to trace focus events during tab cycling. Pay attention to TagInput's onRemove and onAdd callbacks as they may affect focus.
