RTL: editor missing for locked tree grid column

[mankz]

Run this sample in RTL mode, click tree column (no editor visible). Other columns work ok.

Ext.Loader.setConfig({
    enabled: true
});Ext.Loader.setPath('Ext.ux', '../ux');

Ext.require([
    'Ext.data.*',
    'Ext.grid.*',
    'Ext.tree.*',
    'Ext.ux.CheckColumn'
]);

Ext.onReady(function() {
    Ext.QuickTips.init();

    //we want to setup a model and store instead of using dataUrl
    Ext.define('Task', {
        extend: 'Ext.data.Model',
        fields: [
            {name: 'task',     type: 'string'},
            {name: 'user',     type: 'string'},
            {name: 'duration', type: 'string'},
            {name: 'done',     type: 'boolean'}
        ]
    });

    var store = Ext.create('Ext.data.TreeStore', {
        model: 'Task',
        proxy: {
            type: 'ajax',
            //the store will get the content from the .json file
            url: 'treegrid.json'
        },
        folderSort: true
    });
    var cellEditing = Ext.create('Ext.grid.plugin.CellEditing', {
        clicksToEdit: 1
    });

    //Ext.ux.tree.TreeGrid is no longer a Ux. You can simply use a tree.TreePanel
    var tree = Ext.create('Ext.tree.Panel', {
        title: 'Core Team Projects',
        width: 500,
        height: 300,
        renderTo: Ext.getBody(),
        collapsible: true,
        useArrows: true,
        rootVisible: false,
        store: store,
        multiSelect: true,
        plugins : cellEditing,
        selModel: {
            selType: 'cellmodel'
        },
        columns: [{
            xtype: 'treecolumn', //this is so we know which column will show the tree
            text: 'Task',
            width: 200,
            sortable: true,
            dataIndex: 'task',
            locked: true,
            field : {}
        }, {
            text: 'Assigned To',
            width: 150,
            dataIndex: 'user',
            sortable: true,
            field : {}
        }]
    });

});
