It looks like the liquid tag urls.applications.active is not documented anywhere.

Following below is one example of usage that works shared by a customer:

{% if urls.applications.active? %}
	<a class="active" href="{{ urls.applications }}"><Link Description></a>
{% else %}
	<a href="{{ urls.applications }}"><Link Description></a>
{% endif %}

May you review both the 3scale Documentation (2.X On-premises and SaaS) as well as the Liquid Reference on the Admin Portal for this particular liquid tag and any others that we might be potentially missing?
