Apart from this webpage, the test opens another html web page. One test is run
in this web page, and another in the second web page.

// This test fetches resources/http_equiv_accept_ch_lifetime.html as a
// subresource. The response to that webpage contains Accept-CH and
// Accept-CH-Lifetime http-equiv headers.

// Fetching that webpage as a subresource should NOT cause the user-agent to
// persist origin preferences for the client hints specified in Accept-CH
// header.

// Next, to verify if the origin preferences were not persisted by the user
// 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.

// Test is marked as tentative until https://github.com/whatwg/fetch/issues/726
// is resolved.

// First, verify the initial state to make sure that the browser does not have
// client hints preferences cached from a previous run of the test.
