    In https://html.spec.whatwg.org/multipage/#creating-scripts ,
    step 3 describes parsing the script, and step 5 says:
      # Otherwise, report the error using the onerror event handler of
      # the script's global object. If the error is still not handled
      # after this, then the error may be reported to the user.
    which links to
    https://html.spec.whatwg.org/multipage/#report-the-error ,
    which describes what to do when onerror is a Function.
