prepopulated_fields dont work in 2 level+ inlines

[ravique]

class ProductGroupInline(NestedStackedInline):
model = ProductGroup
extra = 1
prepopulated_fields = {'product_group_slug': ('product_group_name',)}

class SubcategoryInline(NestedStackedInline):
model = SubCategory
extra = 1
inlines = [ProductGroupInline]
prepopulated_fields = {'subcategory_slug': ('subcategory_name',)}

class CategoryAdmin(NestedModelAdmin):
inlines = [SubcategoryInline]
prepopulated_fields = {'category_slug': ('category_name',)}

In this sample prepopulated_fields work for SubcategoryInline, CategoryAdmin but not for ProductGroupInline
