Command doesn't work in deno task but works outside of deno task

The command in question:

(find . -name '*.js'; find . -name '*.as') | grep -v bundle | xargs wc -l | sort

(find . -name '*.js'; find . -name '*.as') | grep -v bundle | xargs wc -l | sort

(find . -name '*.js'; find . -name '*.as') | grep -v bundle | xargs wc -l | sort

(find . -name '*.js'; find . -name '*.as') | grep -v bundle | xargs wc -l | sort

Run it in Terminal.app, it works. Run it in Deno, it freezes! This changes when I remove the () to join two commands together.
