useInfiniteScroll 在第一次请求还未返回时，快速切换到其他组件，会造成无限循环的请求

此处会默认执行一次setTimeout，触发函数scrollMethod，当页面被销毁时，判断条件将永久成立，会一直触发loadMore

Start at the useInfiniteScroll entry point and reproduce a rapid switch or unmount while the first request is still pending. Trace the delayed scrollMethod and loadMore calls, then verify that destroying the page stops further requests and add a regression test for this sequence.
