A bug report

What is the current behavior?

When submiting a form after having unmounted/mounted an input field, the fields' validation isn't triggered if you submit the form without having changed the value of the field

What is the expected behavior?

All fields within the component should be validated when clicking submit.

Sandbox Link

In this example there's an input field that requires a value. The first time you click 'show input' and try to submit the form the validation works as expected. However once you hide and show the input field (by using the checkbox), and then submit the form without changing value, the form submits without validating the field: https://codesandbox.io/s/zn8z9z52p

研究方向
Investigate how redux form handles field registration on mount/unmount, focusing on the Field component and reducer logic. Use the provided sandbox to reproduce the issue and trace the validation flow. Look for updates to form state when fields are re mounted and check if validation is triggered on submit. Consider searching for related issues or comments in the repository.
