Form.Item 在 didMount 时注册，这使得同步注册的 Form.Item renderProps 在字段注册事前 render 存在时序问题。

Hi. @zombieJ I noticed that this issue was put forward in 2020, which is quite a long time ago. Is there any plan to fix this bug?

Translation of the subject: Form.Item renderProps can't get the field in the first render

This is affecting me too.

I get do getFieldsValue(true), but then I lose type safety because it return any instead of Values.

[alienzhangyw]

form.getFieldsValue(true) don't return the initialValues in Form props after calling form.resetFields() with all fields untouched

form.getFieldsValue()在第一次渲染时。不能正常获取到initialvalue的值， 如果这个formitem的内容是在抽屉中，在第二次点开抽屉的时候，才能正常获取到initialvalue的值。例子 ：https://codesandbox.io/s/ji-ben-shi-yong-antd-4-21-7-forked-6bnobg?file=/demo.js
这个首次渲染的问题 啥时候才能修复🤔 👀
