I would recommend workaround until this is fixed. Systemd is able to restart the service on ABRT termination, where it was not intended to stop. It will still make limited outage, but much less noticeable than if waiting for manual restart.
Run command:
systemctl edit named.service
Then inside editor, write line between comments:
[Service]
Restart=on-abnormal
Save and quit the editor
Double check the change is active:
systemctl show named.service -p Restart
