Enable fullscreen control and control position with options prop:

const options = {
    fullscreenControl: true,
    fullscreenControlOptions: {
        position: 10
    }    
};

<GoogleMap
    center={this.props.center}
    zoom={this.props.zoom}
    options={options}
    >
    {this.renderMarkers()}
</GoogleMap>

Expected:

• A React component should render with proper control for fullscreen mode, with markers in the correct position.
• A click on the fullscreen control should render the component in fullscreen.
• Markers are correctly positioned while in fullscreen mode.
