Can't kill any processes when --raw is passed

• Description: With concurrently -r -k npm:parcel:dev npm:serve I can't exit with any kind of input, but the same without -r works fine with e.g. Ctrl+C.
• Expected Behavior: I wouldn't expect the --raw argument, which ostensibly just affects printing, to affect what my inputs are able to do.
• Environment: concurrently 8.0.1 on Windows 10. reproduced with powershell and cmd.exe, also in windows terminal and VS Code's integrated terminal.
• Reproduction: Try the command above, where parcel is any parcel command and serve is e.g. nodemon

Thanks!
