Nav list contains invisible modlock link

[jonoaldersonwp]

The horizontal list of links at the bottom of this template - ​https://wordpress.org/support/forums/ - contain a link to ​https://wordpress.org/support/view/taggedmodlook/ which omits an anchor text.

Specifically, the current output is:

<li class="view"><a href="https://wordpress.org/support/view/taggedmodlook/"></a></li>

This link should be removed.
