Remove not hide nav links from Desktop view when Tabs enabled

[ghost]

Description

When the Tabs feature is enabled:

feature:
  tabs: true

L2 (and deeper) links from the nav section are hidden from the user but remain in the HTML. The browser does not show this, but every page links to every other page.

As a consequence “link authority” (SEO term) gets distributed evenly from the site root to all pages on the site.

Expected behavior

Links not displayed to the user are removed from the HTML in the Desktop view. (In Mobile views they are required for navigation.)

By nominating the Desktop bot as the preferred crawler for our site, we would see link authority flowing to the pages most prominent to the visitor.

Actual behavior

Nav links remain in the HTML; link authority dissipates across the site.

Steps to reproduce the bug

1. Config: ensure nav section contains at least one child level
2. Config: enable Tabs feature
3. Compile site and browse in Desktop view
4. Observe presence in HTML of links not visible to user

Tabs are only shown for the desktop breakpoint. As soon as the navigation is moved into the drawer (tablet and below), there are no more tabs but the normal navigation. This is by design, as for example the page navigation should work at portrait and landscape orientation on a tablet. They cannot be removed.
