| // preferences for the client hints specified in Accept-CH header. |

| // agent, this test fetches resources/do_not_expect_client_hints_headers.html |
| // in a new window. Fetching of |
| // resources/do_not_expect_client_hints_headers.html |
| // verifies that the user agent does not send the client hints in the request |
| // headers. |

| // hints preferences cached from a previous run of the test. |
