Markers not being removed from MarkerClusterer

[ghost]

Consider this example:

The Sydney marker should just stay in place, but after every even click, the cluster number increments.
I suspect that removing is not handled properly...

React               = require 'react'
{GoogleMap, Marker} = require 'react-google-maps'
MarkerClusterer     = require 'react-google-maps/lib/addons/MarkerClusterer'

Sydney =
    lat: -33.8539657
    lng: 150.9485251

ClusterDemo = React.createClass

    getInitialState: ->
        inside: false

    handleToggle: ->
        @setState
            inside: !@state.inside

    render: ->
        <div>
            <div>
                <Button onClick={@handleToggle}>Toggle</Button>
            </div>
            <div style={height: '200px', width: '600px'}>
                <GoogleMap
                        containerProps={{style: {height: '100%'}}}
                        defaultZoom={3}
                        defaultCenter={Sydney}
                    >
                    <MarkerClusterer ref="cluster">
                        {if @state.inside
                            <Marker position={Sydney} />
                        }
                    </MarkerClusterer>

                    {if !@state.inside
                        <Marker position={Sydney} />
                    }
                </GoogleMap>
            </div>
        </div>

module.exports = ClusterDemo

Why there are no tests for simple cases like this? @tomchentw
