        <h1>Pointer Events - lostpointercapture when capturing element is removed</h1>
        <h4>
            Test Description:
            This test checks if lostpointercapture is fired at the document when the capturing node is removed from the document.
            Complete the following actions:
            <ol>
                <li>Press and hold left mouse button over "Set Capture" button. "gotpointercapture" should be logged inside of the black rectangle.
                <li>"lostpointercapture" should be logged inside of the black rectangle after a short delay.
            </ol>
