#### Type
`inconsistency` for common use cases.
`bug` for projects relying on correct DOM emissions.

#### Description
It's unclear to me if the following is a known issue or not.
Take in consideration the snippet below:
```jsx
<input type="checkbox" defaultChecked={true} />
```
#### Current Behavior
Setting the `defaultValue` prop on inputs of other types sets both the `value` and `defaultValue` attribute on the DOM element.

When setting the `defaultChecked` prop on inputs of type `checkbox` only the `checked` attribute is correctly set, leaving the `defaultChecked` attribute unchanged.

#### Expected Behaviour
Like mentioned above, the expected behavior would be for the `defaultChecked` prop to set both the `checked` and `defaultChecked` attributes on the corresponding DOM node (like it's the case with the `defaultValue` prop).

state = {changed: false};
      handleChange = () => {
        this.setState({
          changed: true,
        });
      };
      componentDidUpdate() {
        sharedParent.appendChild(container2);
      }
      render() {
        return (
          <div>
            <input
              ref={n => (bNode = n)}
              type="radio"
              name="fruit"
              checked={false}
              onChange={this.handleChange}
