  <h1>Description</h1>
  <p>This test validates that when in "window-controls-overlay" mode, the 'titlebar-area-*' CSS environment variables
    match the values returned by navigator.windowControlsOverlay.getTitlebarAreaRect().</p>
  <h1>Manual Test Steps:</h1>
  <p>
    <ol>
      <li> Install this app, and toggle into "window-controls-overlay" mode.</li>
      <li> Upon toggling into "window-controls-overlay" mode, the test will validate that the CSS enviroment variable
        values match the JavaScript API.</li>
    </ol>
  Note: This test will automatically timeout and fail if not completed within 60 seconds.
