[Dnsmasq-discuss] Cannot look up disa.mil (dnssec related)

I'm unable to look up *.disa.mil when using dnsmasq - I'm hoping that we 
can figure out why that is.

I have dnsmasq configured to use Cloudflare's 1.1.1.1 as its upstream 
DNS server; dnsmasq is running on 192.168.0.1.

Here are some a couple tests demonstrating the problem:
------
$ dig disa.mil @192.168.0.1 +dnssec +short
<no output>
$ dig disa.mil @8.8.8.8 +dnssec +short
156.112.108.76
A 8 2 7200 20181117145327 20181018145327 52983 disa.mil.

[candrews at craigatwork vars]$ dig disa.mil @1.1.1.1 +dnssec +short
156.112.108.76
------
So looking it up using Google's 8.8.8.8 or Cloudflare's 1.1.1.1 with 
dnssec works, but not with dnsmasq.
