| 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. |

| https://html.spec.whatwg.org/multipage/#report-the-error , |
| which describes what to do when onerror is a Function. |
