https://gerrit.wikimedia.org/r/gitweb?p=mediawiki/extensions/ClickTracking.git;f=modules/jquery.clickTracking.js;hb=HEAD#l12 says
        // Attach a timestamp to the tracked event and append it to the
        // logged event array (mw.tracked).

But there's no mw.tracked key! Just:
        // Attach a timestamp to the action's data (some tracked event)
        // and remember it for $.getTrackedActions()

(I have a local branch fixing this with a few other comment improvements.)
