>  This adds a test that a stylesheet that failed to load is considered

>  SecurityError.  This aligns with the specifications:
>  - cssRules checks the `origin-clean` flag:
>    https://drafts.csswg.org/cssom/#dom-cssstylesheet-cssrules
>  - This is set to true iff CORS-same-origin:
>    https://html.spec.whatwg.org/multipage/links.html#link-type-stylesheet
>  - CORS-same-origin is false for "error" responses:
