[FIXED] Extjs 5.0.1 - Cannot expand combobox in cell editing grid panel in IE8/IE9 browser

Hi,

I am using the extjs 5.0.1 to test this. I loaded a cell editing grid with combobox editor in IE8 and IE9, When I click on a cell the drop down shows, but when I mouse-click to expand the drop down, the editing mode go away. Same problem with the cell editing grid in Kitchen Sink. Is this a bug?

Code:

Ext.onReady(function () {


            Ext.define('KitchenSink.model.State', {
                extend: 'Ext.data.Model',


                fields: [
                    'abbr',
                    'state',
                    'description',
                    'country'
                ]
            });


            Ext.define('KitchenSink.store.States', {
                extend: 'Ext.data.ArrayStore',


                alias: 'store.states',


                model: 'KitchenSink.model.State',


                storeId: 'states',


                data: [
                    [0, 'AL', 'Alabama', 'The Heart of Dixie'],
                    [1, 'AK', 'Alaska', 'The Land of the Midnight Sun'],
                    [2, 'AZ', 'Arizona', 'The Grand Canyon State'],
                    [3, 'AR', 'Arkansas', 'The Natural State'],
                    [4, 'CA', 'California', 'The Golden State'],
                    [5, 'CO', 'Colorado', 'The Mountain State']
                ]
            });


            var panel = Ext.create("Ext.grid.Panel", {
                title: 'states',
                width: 680,
                height: 350,
                store: { type: 'states' },
                plugins: [new Ext.grid.plugin.CellEditing({
                    clicksToEdit: 1
                })],
                columns: [
                    {
                        header: 'State',
                        dataIndex: 'state',
                        flex: 1,
                        editor: {
                            xtype: 'combobox',
                            fieldLabel: 'Select a state',
                            displayField: 'state',
                            anchor: '-15',
                            labelWidth: 130,
                            store: {
                                type: 'states'
                            },
                            queryMode: 'local'
                        }
                    }
                ]
            });


            Ext.create("Ext.tab.Panel", {
                title: "configuration details",
                width: 700,
                height: 400,
                items: [panel],
                renderTo: Ext.getBody()
            });
        });
