Sidebars on custom product taxonomy archives

I have a couple of custom taxonomies that are properly registered to the “product” post type. Your code does not allow their archives to display the shop sidebar.

As far as I can see, it’s your function woostify_sidebar_class() which is causing the problem as its check for a Woocommerce page is

if ( class_exists( 'woocommerce' ) && ( is_shop() || is_product_category() || is_product_tag() ) )

It would be more helpful if the check was

if ( class_exists( 'woocommerce' ) && ( is_shop() || is_tax( get_object_taxonomies( 'product' ) ) ) )

Cheers
