Steps to reproduce:

1. Configure a Buildkite pipeline to build this repository using pipeline.yml.
2. Start an agent by running BUILDKITE_AGENT_TOKEN=<xyz> ./start-bootstrapped-agent.sh
3. Trigger a new build of the pipeline
4. After the command has been running for 10 seconds, click Cancel button for the step
5. Observe that job output ends with line Received cancellation signal, interrupting
   • expected to see lines:

   Terminated
   🚨 Error: The command was interrupted by a signal

6. Observe that agent logs include the error message:
