I use the openssl rand -base64 10 command to generate passwords. When I double click to select stdout, and hold the Cmd key to copy it to clipboard, a DNS query is issued for any string before a / character.

I removed all Smart Selection rules, but the behavior persists (as can be seen with tshark -Y "dns" or tcpdump "udp port 53" or equivalent.

I would like to turn off the smart selection behavior, or at least stop it from issuing dns requests for what it thinks are hostnames.
