        <h1>Pointer Events Capture Test - capture and relatedTarget</h1>
        <h4>
            Test Description: This test checks if setCapture/releaseCapture functions works properly. Complete the following actions:
            <ol>
                <li> Put your mouse over the lower rectangle. pointerover should be received for the purple rectangle
                <li> Press and hold left mouse button over "Set Capture" button
                <li> Put your mouse over the upper rectangle. pointerover should be received for the black rectangle
                <li> Release left mouse button to complete the test.
            </ol>
        </h4>
        Test passes if the proper behavior of the events is observed.
