HarmonyOS Window的setWindowSystemBarProperties方法设置状态栏颜色失败

static setStatusBarProp(win: window.Window) {
  let sysBarProps: window.SystemBarProperties = {
    statusBarColor: '#00FFFFFF',
    statusBarContentColor: '#FF000000',
    //isStatusBarLightIcon: false,
  };
  win.setWindowSystemBarProperties(sysBarProps, (err: BusinessError) => {
    let errCode: number = err.code;
    if (errCode) {
      console.error('[StaticUtils] Failed to set the system bar properties. Cause: ' + JSON.stringify(err));
      return;
    }
    console.info('[StaticUtils] Succeeded in setting the system bar properties.');
  });
}

深色模式下，无法将状态栏图标设置成黑色。
