#### 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).
