**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.

const name = props.name;
  if (props.type === 'radio' && name != null) {
    let queryRoot: Element = rootNode;
    while (queryRoot.parentNode) {
      queryRoot = ((queryRoot.parentNode: any): Element);
    }
    
    
    
    
    
    
    
    const group = queryRoot.querySelectorAll(
      'input[name=' + JSON.stringify('' + name) + '][type="radio"]',
    );
    for (let i = 0; i < group.length; i++) {
      const otherNode = ((group[i]: any): HTMLInputElement);
      if (otherNode === rootNode || otherNode.form !== rootNode.form) {
        continue;
      }
      
      
      
      
      const otherProps = getFiberCurrentPropsFromNode(otherNode);
      invariant(
        otherProps,
