// 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.
