        <h1>Pointer Events Capture Test - release capture on pointercancel</h1>
        <h4>
            Test Description: This test checks if setCapture/releaseCapture functions works properly. Complete the following actions:
            <ol>
                <li> Touch black rectangle and do not release your touch
                <li> Move your touch to scroll the page. "lostpointercapture" should be logged inside of the black rectangle immediately after "pointercancel"
            </ol>
        </h4>
        Test passes if the proper behavior of the events is observed.
