**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.

setUntrackedValue = Object.getOwnPropertyDescriptor(
      HTMLInputElement.prototype,
      'value',
    ).set;
    setUntrackedChecked = Object.getOwnPropertyDescriptor(
      HTMLInputElement.prototype,
      'checked',
    ).set;
    React = require('react');
    ReactDOM = require('react-dom');
    ReactDOMServer = require('react-dom/server');
    container = document.createElement('div');
    document.body.appendChild(container);
  });
  afterEach(() => {
    document.body.removeChild(container);
  });
  it('should warn for controlled value of 0 with missing onChange', () => {
    expect(() => {
      ReactDOM.render(<input type="text" value={0} />, container);
    }).toWarnDev(
      'Failed prop type: You provided a `value` prop to a form field without an `onChange` handler.',
    );
  });
