Operating system and its version

Others

Browser and its version

Chrome

Sandbox to reproduce

https://stackblitz.com/edit/react-ts-ufnhw9?file=App.tsx

What happened?

复现方法是：

  1. 打开上面的 demo
  2. 点添加按钮，添加三项内容，并分别输入一些值
  3. 删除第二项
  4. 发现此时第三项的值也异常了

预期行为：

点击删除之后，第三项的值保持不变，仅第二项被删除掉

额外一点补充：

把 Form 上的 preserve={false} 去掉就行为正常了 疑似 rc-field-form 的问题

Research direction
Investigate the interaction between Form.List and the preserve prop in antd mobile. The bug occurs when preserve={false} is set. Start by examining the Form component's implementation in the antd mobile source, particularly how Form.List handles deletion. Also check the upstream rc field form repository for any related issues or fixes. The provided StackBlitz demo (https://stackblitz.com/edit/react ts ufnhw9) contains a reproduction. Look at the comments on the issue for any additional insights from maintainers.
