I've just taken a look at the other two tickets and it looks like #3019 is
the most recent one but is lacking the conversation/ticket history. As an
outsider I can see that's three open tickets for one feature with a chain like
#2420 -> #2682 -> #3019 .
I think at the very least this ticket (#2420) can be closed as it's quite
definitely superceded.---
