Breadcrumb.MenuItemTemplateSelector

I have a scenario where I need to change the content of a breadcrumb MenuItem based on data type. My problem is, the breadcrumb control appears to ignore the MenuItemTemplateSelector property.

My code basically looks like the following:

<local:BreadcrumbItemTemplateSelector x:Key="BreadcrumbItemTemplateSelector" />
<nav:Breadcrumb x:Name="breadcrumb"
RootItem="{Binding Path=Tree}"
ItemTemplate="{StaticResource BreadcrumbItemTemplate}"
ItemContainerStyle="{StaticResource HomeBreadcrumbItemStyle}"
MenuItemTemplateSelector="{StaticResource BreadcrumbItemTemplateSelector}"
MenuItemContainerStyle="{StaticResource MenuItemContainerStyle}" />
