| // browser side of Background Fetch doesn't yet support performing CORS checks |
| // (crbug.com/711354). This is non-spec-compliant, which is why it is tested |
| // here instead of in web-platform-tests. |
| |
| // This is not a comprehensive test of CORS preflight detection - it is just |
| // intended to check that detection is enabled. |
