Styles don't work on Map component.

[koala-lava]

<Map onAPIAvailable={function () { console.log('API loaded'); }} center={[51.70858418, 94.43314205]} zoom={17} style={{
                width: '100%',
                height: '200px'
            }}>
                <Marker lat={this.props.lat} lon={this.props.lon} />
 </Map>

Used style prop. How can I style this Map component? I mean hardcoded width and height is not an option for me.
