    <h2>Description</h2>
    <p>This test that movementX/Y do not jump by a large value when exiting and re-entering the window.</p>
    <hr/>

    <h2>Manual Test Steps:</h2>
    <p>
        <ol>
            <li>Make sure the window is not maximized.</li>
            <li>Click to start Test.</li>
            <li>Move the mouse slowly out of the window.
            <li>Move as fast as needed to a different location outside the window at least 100 pixels away</li>
            <li>Slowly re-enter the window.</li>
            <li>Click again to end tests.</li>
        </ol>
