Bash.exe processes not killed on windows runner

Summary

• Windows Runner
• Executor is set to Shell
• Shell = bash.exe

Processes scripted in this bash.exe are not killed when a job is terminated

Steps to reproduce

• With the above configuration, set a ci job to create sub-processes of the bash.exe
• Stop/terminate the job (rails UI)
• Job is halted, but bash.exe processes on runner continue to execute

.gitlab-ci.yml

Add the job definition that is failing here

Actual behavior

Processes continue running after the job is stopped

Expected behavior

Processes are killed/terminated when the runner job is stopped

Relevant logs and/or screenshots

job log

Add the job log

Used GitLab Runner version

Possible fixes

Possible workaround, if coreutils is available on Windows, use timeout
