[4.1.1] How to align textfield with combobox/datefield?

[Ex_Soft]

Textfield isn't aligned with combobox/datefield:

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

    Ext.create("Ext.window.Window", {
        title: "Test Ext.layout.container.Anchor",
        autoShow: true,
        layout: "fit",
        border: 0,
        items:[{
            xtype: "form",
            frame: true,
            bodyStyle: "padding: 5px 0 0 0",
            items: [{
                xtype: "textfield",
                fieldLabel: "textfield",
                anchor: "100%"
            }, {
                xtype: "combobox",
                fieldLabel: "combobox",
                anchor: "100%"
            }, {
                xtype: "datefield",
                fieldLabel: "datefield",
                anchor: "100%"
            }]
        }]
    });
});

P.S. BTW, textfield is aligned if window will be resized.
