ASPxFormLayout - The AlignItemCaptionsInAllGroups option does not work for layout items in the TabbedLayoutGroup container

I have a problem with aligning tab items among with other item in group2.

C#
@Html.DevExpress().FormLayout(s =>  
{  
    s.Name = "settings1";  
    s.Width = Unit.Percentage(100);  
    s.AlignItemCaptionsInAllGroups = true;  

    s.Items.AddGroupItem(ng =>  
    {  
        ng.Name = "group1";  
        ng.Caption = "Group 1";  
        ng.Items.Add(i =>  
        {  
            i.Name = "item1";  
            i.CaptionSettings.Location = LayoutItemCaptionLocation.Top;  
            i.RequiredMarkDisplayMode = FieldRequiredMarkMode.Hidden;  
            i.Caption = "Item 1";  
            i.NestedExtensionType = FormLayoutNestedExtensionItemType.TrackBar;  

            var tbSettings = (TrackBarSettings)i.NestedExtensionSettings;  
            tbSettings.Width = Unit.Percentage(50);  
            tbSettings.Properties.MaxValue = 5;  
            tbSettings.Properties.MinValue = 0;  
            tbSettings.Properties.ScalePosition = ScalePosition.RightOrBottom;  
            tbSettings.Properties.ValueToolTipPosition = ValueToolTipPosition.RightOrBottom;  
            tbSettings.Properties.LargeTickInterval = 5;  
            tbSettings.Properties.ValueType = typeof(int);  
        });  
    });  

    s.Items.AddGroupItem(g =>  
    {  
        g.Name = "group2";  
        g.Caption = "Group 2";  
        g.Width = Unit.Percentage(100);  
        g.AlignItemCaptions = true;  

        g.Items.Add(i =>  
        {  
            i.Name = "item2";  
            i.Caption = "Item 2";  
            i.NestedExtensionType = FormLayoutNestedExtensionItemType.ComboBox;  

            var cbSettings = (ComboBoxSettings)i.NestedExtensionSettings;  
            cbSettings.Properties.Items.Add("Option 1");  
            cbSettings.Properties.Items.Add("Option 2");  
            cbSettings.Properties.Items.Add("Option 3");  
            cbSettings.Properties.Items.Add("Option 4");  
            cbSettings.Properties.ClientSideEvents.SelectedIndexChanged = "OnSelectedIndexChanged";  
        });  

        g.Items.AddTabbedGroupItem(tg =>  
        {  
            tg.Name = "tabGroup1";  
            tg.Width = Unit.Percentage(100);  
            tg.ShowGroupDecoration = false;  

            tg.Items.AddEmptyItem();  
            tg.Items.Add(i =>  
            {  
                i.Name = "item3";  
                i.ShowCaption = DefaultBoolean.True;  
                i.Caption = "Long Text";  
                i.NestedExtensionType = FormLayoutNestedExtensionItemType.ComboBox;  

                var cbSettings = (ComboBoxSettings)i.NestedExtensionSettings;  
                cbSettings.Properties.ValueType = typeof(int);  
                cbSettings.Properties.ValueField = "Id";  
                cbSettings.Properties.TextField = "Country";  
            });  

            tg.Items.Add(i =>  
            {  
                i.Name = "item4";  
                i.Caption = "Super Long Text";  
                i.NestedExtensionType = FormLayoutNestedExtensionItemType.ComboBox;  
                i.ShowCaption = DefaultBoolean.True;  

                var cbSettings = (ComboBoxSettings)i.NestedExtensionSettings;  
                cbSettings.Properties.ValueType = typeof(int);  
                cbSettings.Properties.ValueField = "Id";  
                cbSettings.Properties.TextField = "Name";  
            });  

            tg.Items.Add(i =>  
            {  
                i.Name = "item5";  
                i.Caption = "Very Very Very Long Text";  
                i.NestedExtensionType = FormLayoutNestedExtensionItemType.ComboBox;  
                i.ShowCaption = DefaultBoolean.True;  

                var cbSettings = (ComboBoxSettings)i.NestedExtensionSettings;  
                cbSettings.Properties.ValueType = typeof(int);  
                cbSettings.Properties.ValueField = "Id";  
                cbSettings.Properties.TextField = "Title";  
            });  
        });  
    });  

    s.Items.Add(i =>  
    {  
        i.Name = "submitButton";  
        i.ShowCaption = DefaultBoolean.False;  
        i.HorizontalAlign = FormLayoutHorizontalAlign.Center;  

        i.NestedExtensionType = FormLayoutNestedExtensionItemType.Button;  
        var btnSettings = (ButtonSettings)i.NestedExtensionSettings;  
        btnSettings.UseSubmitBehavior = true;  
        btnSettings.Width = Unit.Pixel(100);  
        btnSettings.Text = "Go";  
    });  
}).GetHtml()  

I thought that with AlignItemCaptionsInAllGroups property enabled it should fix by itself.
