Previously, cmd+click (or ctrl+click) on the
<a>
tag within job rows on the jobs index page would double-open the page: once in a new tab (as cmd+click does) and another in the same tab (as it would trigger the{{on "click"}}
Ember event for the job row.This checks to make sure the clicked element wasn't the anchor tag itself, and if it is, it returns early.
NB: it's a bad practice, generally, to have non-interactive elements like table rows be clickable! However this follows a long-standing convention in the Nomad UI that users may be used to from years of use, and has more than one highly accessible fallback.
