Repro steps

ng new --skip-install -sg -it my-app && cd my-app

yarn install

yarn start --aot --open

CTRL+C

Observed behavior

When executing locally installed ng via npm start or yarn start

Server is not terminated and keeps running. Extensive hunt for hanging Node PID is needed, followed by killing the process with kill PID ouch!

when server is run via globally installed ng it is killed as expected....

Desired behavior

When yarn ng serve is terminated, it should be properly terminated

Mention any other details that might be useful (optional)
