& did not start a character reference. 
(& probably should have been escaped as &.)

Though a very minor problem and compatible on major web browsers, it becomes important in the case of browsers (which we shouldn't ignore being good web devs) which would break the parsing. Lenient browsers like Firefox, Chrome, Safari don't have a problem, but we should always consider the fact that there shouldn't be a problem in the webpage design and layout. So a small fix would be.

<li target="https://wiki.mozilla.org/Auto-tools/New_Contributor">Tools &amp; Automation
          <div class="extra" data-l10n-id="py-tools-extra"></div>
</li>

Though HTML5 allows you to leave it unescaped, but only when the data that follows does not look like a valid character reference. However, it's better just to escape all instances of this symbol than worry about which ones should be and which ones don't need to be.
