确保 fake timers 在测试失败时恢复。
当前 jest.useRealTimers() 只在测试正常结束时执行。若任一断言或异步操作抛错，fake timers 会保留并影响后续测试。使用 try/finally 包住测试主体，并在 finally 中恢复真实计时器。

Summary
Problem
The global Tab handler currently calls focusMenu() whenever the overlay has not yet received focus. It does this for both Tab and Shift+Tab. As a result, Shift+Tab from the trigger is prevented and focus is forced forward into the menu instead of allowing the user to move to the previous control.
