Modal doesn't pass `style` property to div

### Issue description

- version `#4.6.2`
- components: `Modal`

### Steps to reproduce issue

```jsx
<Modal isOpen={isOpen} toggle={this.onToggle} style={{ maxWidth: '95%' }}>
```
the `style` property doesn't apply on the final rendered `div` element. I checked the source code, and found that the problem does exist.

is it intended?
