// Here's the set-up for this test:

// Step 1 (first window) Set client hints in the same header that clears them.

// Step 2 (first window) Open second window.

// Step 3 (second window) Message first window about client hints sent.

// Step 4 (first window) Asserts client hints not sent.

    // Step 4

    window.addEventListener("message", t.step_func(e => {

        assert_equals(e.data, "MissingDeviceMemory");

        t.done();

    }), {once: true});

    // Step 2

    new_window = window.open("/client-hints/clear-site-data/resources/check-client-hints.py");

    t.add_cleanup(new_window.close);

}, "Setting critical client hints after Clear-Site-Data for cache shouldn't allow the client hints to take.");
