#### 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 = {value: 'lion'};
      a = null;
      b = null;
      change(newValue) {
        
        
        
        
        this.b.click();
      }
      render() {
        return (
          <div>
            <input
              type="text"
              ref={n => (this.a = n)}
              value="lion"
              onChange={e => this.change(e.target.value)}
            />
            <input
              type="checkbox"
              ref={n => (this.b = n)}
              checked={true}
              onChange={() => {}}
            />
          </div>
        );
      }
    }
    const container = document.createElement('div');
