testing-farm request --test /Sanity/test1 --test /Sanity/test2 only runs /Sanity/test2

I requested a test run using this command testing-farm request --context distro=rhel8.6 --test /Sanity/timer --test /Sanity/systemctl-smoke --compose RHEL-8.6.0-Nightly --plan all-no-buildroot --arch x86_64 for https://pkgs.devel.redhat.com/cgit/tests/systemd and it looks like only the last test specified with --test was run. Run results here https://artifacts.osci.redhat.com/testing-farm/00f83ac4-aadd-48d0-a558-65a7a273d417

Is --test only accepted once?
