It is true that when tracking on click, `href` is required for outbound links, however, as liz has mentioned and as [mentioned inline in the code](https://github.com/Wikia/app/blob/dev/resources/wikia/modules/tracker.js#L316-L318) and [in the documentation](https://internal.wikia-inc.com/wiki/WikiaTracker#Special_Case:_External_Links), tracking on click has been deprecated in favor of tracking on mousedown.
