Error when using value and custom RadioGroup component by AntD

### Are you submitting a **bug report** or a **feature request**?

Bug

### What is the current behavior?
I get an error when using custom Radio/Group component (from AntD library)

### What is the expected behavior?

I don't expect any warning or error.

### What's your environment?

I have encountered it with a version 3.7.0 where the `input` prop didn't yet contain the `type` attribute and had to be inserted manually onto the input (and therefore to avoid repetition, one would simply put the type on input, but not the Field), but the problem is same with latest 6.3.0 as in the sandbox provided.
