The feature tab in main page on mouse hover shows as below.
<a href="?tab=featured" title="Looking for more featured questions? Browse the <a href=&quot;/questions?sort=featured&quot;>complete list</a>.">featured</a>
However, you can see there is un-required link reference to feature-tab. Instead it should be as simple as Looking for more featured questions? Browse the complete list. without link ref*
Or like in question/feature tab hover Questions with open bounties.
Note:- Link provided in tooltip is completely useless there and serves no purpose..
