Your suggestion to limit bind will work for me.
I wasn't sure how to tell bind to not listen on an interface.
Bind defaults to: listen-on { any; };
I modified /etc/bind/named.conf.options by adding the following line:
listen-on port 53 { 127.0.0.1; 192.168.2/24; };
This should restrict bind to localhost and my main network, and should
prevent it from attaching to the virbr0 interface.
After installing the current version of dnsmasq (2.90-0ubuntu0.22.04.1)
and rebooting, it looks like everything is working properly now.
Thanks for all the help with this issue!

Title:
dnsmasq-base causes network device virbr0 to shut down
Status in dnsmasq package in Ubuntu:
New
Bug description:
Installing dnsmasq-base v2.90-0ubuntu0.22.04.1 causes network device
virbr0 to shut down during the boot-up process. Device virbr0 is
installed by the libvirtd daemon. libvirtd gets an unexpected error
when dnsmasq is called and then the address record for virbr0 is
withdrawn.
This problem goes away when reverting back to dnsmasq-base v2.86-1.1
The attached text file provides relevant status reports which
illustrate this problem. (status is shown for the system when using
dnsmasq-base v2.90-0ubuntu0.22.04.1 when the problem occurs and then
when the system operates correctly using dnsmasq-base v2.86-1.1)
