I have a link on my website that, when I click on it in Chrome v16.0.912.75 or Safari v5.0.6 (5533.22.3) becomes highlighted by a blue border.

<li><a href="http://example.com/" accesskey="1" tabindex="1">Home</a></li>
Clicking results in the following:

Why is the right side of the cell not also highlighted?
