Confirmed this is a valid bug. Had a family member open a tor tab and paste an onion site into that tab. As I dont use Brave... I instantly saw the .onion address in my DNS query logs. Unbound DNS on my router is configured to NXDOMAIN those requests. Maybe I will instead add that zone and redirect to a funny page.
