Submenu navbar anchor active class does not get applied

[chrisdel101]

The class #navbar a.active applies styles but the active class is not being applied correctly. In this example I believe the "Guide" should be set to active, not the "Getting Started"

I think is this actually operating as expected, as per the logic in the templates like:
<a href="/{{ page.lang }}/starter/installing.html"{% if page.menu == 'starter' %} class=" "{% endif %}>Getting started</a>

I think this menu would be better if the top level anchors became active when opened. The way it is now is not intuitive like the full size menu is.
