Highcharts 3.08 drilldown with multiple parent series - highcharts

Question

I am making my first drilldown charts with Highcharts, and I just installed version 3.09, in which drilldown has built-in support. The drilldown chart will be part of a page that already contains multiple charts. All charts have 3 series (State, Region, Sub-region) with data populated dynamically.
The problem is that the drilldown module doesn't seem to support multiple parent series. In my case, if I click on a column for a specific series (say, State), then the State series will disappear and its drilldown will appear, but the other series (Region, Sub-region) are still displayed and the graphic doesn't make any sense then. See this jsFiddle: http://jsfiddle.net/jmunger/6bBzt/ .
$(function () {
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Monthly Average Rainfall'
},
subtitle: {
text: 'Source: WorldClimate.com'
},
xAxis: {
categories: [
'CAT 1',
'CAT2'
]
},
yAxis: {
min: 0,
title: {
text: 'Rainfall (mm)'
}
},
tooltip: {
headerFormat: '<span style="font-size:10px">{point.key}</span><table>',
pointFormat: '<tr><td style="color:{series.color};padding:0">{series.name}: </td>' +
'<td style="padding:0"><b>{point.y:.1f} mm</b></td></tr>',
footerFormat: '</table>',
shared: true,
useHTML: true
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0
}
},
series: [{
name: 'Tokyo',
data: [{y:49.9, drilldown:'tokyo 1'}, {y:71.5, drilldown:'tokyo 2'}]
}, {
name: 'New York',
data: [{y:49.9, drilldown:'ny 1'}, {y:71.5, drilldown:'ny 2'}]
}],
drilldown:{
series: [{
id: 'tokyo 1',
data: [{y:39.9, name:'name1'}, {y:31.5, name:'name2'}]
}, {
id: 'tokyo 2',
data: [{y:39.9, name:'name1'}, {y:31.5, name:'name2'}]
},
{
id: 'ny 1',
data: [{y:39.9, name:'name1'}, {y:31.5, name:'name2'}]
}, {
id: 'ny 2',
data: [{y:39.9, name:'name1'}, {y:31.5, name:'name2'}]
}]
}
});
});
How can I make sure that all parent series are hidden when I perform a drilldown, and that they are then restored correctly when I drill up?

It's bug in 3.0.8 and 3.0.9 version of drilldown. It's already fixed on master branch, see: http://jsfiddle.net/6bBzt/1/
