StyleSelector null-return bug

[Aleksey]

Have view with RadGridView with RowStyleSelector:

<telerik:RadGridView
 ...
      RowStyleSelector="{StaticResource myStyle}"
...
/>

And resources is:

<Grid.Resources>
  <localss:MyStyle x:Key="myStyle">
    <localss:MyStyle.UneditableStyle>
      <Style TargetType="telerik:GridViewRow" BasedOn="{StaticResource GridViewRowStyle}">
        <Setter Property="Background" Value="LightGray" />
      </Style>
    </localss:MyStyle.UneditableStyle>
  </localss:MyStyle>
</Grid.Resources>

RowStyleSelector is next:

public class MyStyle: StyleSelector
{
    public override Style SelectStyle(object item, DependencyObject container)
    {
        var s = item as MyObject;
        if (s == null)
            return null;
        if (!s.Editable)
            return UneditableStyle;
        return null;
    }

    public Style UneditableStyle { get; set; }
}

In Silverlight UI 2013 Q3 appear following bug:
When s.Editable is false, style color (UneditableStyle) row correct.
When s.Editable becomes true, SelectStyle return null , but row was still colored and it's style is UneditableStyle, not default style (no style) as it was in 2013 Q2. But it must be default.

2013Q3SP2 fix it.

Oh, not. Maybe not. Visual Studio option for Silverlight "Reduce XAP size by using application library caching" run old version so I cannot try it now.
