  # Tests the WordPress Core build process on additional operating systems.
  #
  # This is separate from the job above in order to use stricter conditions when determining when to test additional
  # operating systems. This avoids unintentionally consuming excessive minutes. Windows-based jobs consume minutes at a
  # 2x rate, and MacOS-based jobs at a 10x rate.
  # See https://docs.github.com/en/billing/concepts/product-billing/github-actions#per-minute-rates.
  #
  # The `matrix` and `runner` contexts are not available for use within `if` expressions. So there is
  # currently no way to determine the OS being used on a given job.
  # See https://docs.github.com/en/actions/learn-github-actions/contexts#context-availability.
