Product tags undefined

[AgustReon]

Hi,

All products in the store I'm working on have tags on them yet they are all undefined in CartJS.cart

quantity: 3
requires_shipping: true
sku: "6878682"
tags: undefined
taxable: true
title: "Origins India"
total_discount: 0

I can see the tags when I use normal liquid syntax.

{% for item in cart.items %}
  {{item.product.handle}}
  {% for tag in item.product.tags %}
    {{tag}}
  {% endfor %}
{% endfor %}

Is this a bug or is there something required in init to access tags?

If not is there a way to get the handle from CartJS and access {{ all_products[CartJS.cart.items[index].product.handle].tags }}?
