Hello devs
in order to use DOH/DOT, a proxy upstream is configured, when dnsmasq
enables use-stale-cache, some upstream may return error when dnsmasq
tries to refresh the record from upstream after stale cache is sent to
client.
i reported the issue here in dnsproxy project, as this is the DOH proxy
i am currently using. however i've tried many other Go/Rust DOH proxy (
namely doh-client, dns-over-https, dnss, cloudflared) , they all return
error when dnsmasq tries to refresh the record.

only reproducible : if the requesting client is macOS and the upstream
is a DOH proxy, Linux does not have this issue. using a udp upstream
like 1.1.1.1 does not have this issue either.
hope you could take a look at the issue posted.
I think I've found and fixed the problem, but I don't have a macOS
machine to test with, nor have a I configured a DOH proxy, so I'd
appreciate it if you could re-run your tests and see if it works with
the patch in place.
