FYI I've reported a similar (but different) bug: https://bugs.launchpad.net/ubuntu/+source/bind9/+bug/1965521
I believe the workaround that I've offered is slightly more optimal than the 10-second sleep offered above. (It is however reassuring to know that you solved this problem in almost exactly the same way.)
Thanks, Nick.
