This is a bug

What is the current behavior?

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via https://jsfiddle.net or similar (template: https://jsfiddle.net/reactjs/69z2wepo/).

Using 15.2.0 react and react-dom

What is the expected behavior?

Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?

In 15.2.0, extra attributes name and value with empty values are added to the submit button of a form.

It works in 15.1.0.

Uhhh, seems that this was missed on #6406? The culprit here is postMountWrapper in ReactDOMInput.js

node.value = node.value; 🙊

Thanks for catching! I put up something that at least fixes the constant render case. I think we'd always have this problem if you toggled value of these inputs from a real value to undefined so I'm not too worried about trying to handle that.
