研究方向
Examine the Dropdown component implementation, likely in src/modules/Dropdown/Dropdown.js. The issue involves closing behavior and state management when clicking outside vs. programmatic close. Look at the handleClose and handleClickOutside methods. The bug seems to be that closing by clicking outside triggers a different state update than closing via the dropdown's own close mechanism. Investigate the order of state updates and the resetting of selection. Also check the test cases provided in the issue to reproduce.
