 As can be seen on https://make.wordpress.org/cli/handbook/wish-list/, the
 ticket preview script fails when trying to load information for a ticket.
 The tickets exist, but of course reference GitHub issues, not Trac
 tickets.

 Given that these ticket numbers are within existing `<a>` tags, I think
 the hovercard script should skip any already linked tickets.
