HarmonyOS 鸿蒙Next Beta5手机设置状态栏颜色失效

1、Beta2时使用如下方式修改状态栏颜色 显示正常：

window.getLastWindow(context).then((windowClass: window.Window) => {
  try {
    let sysBarProps: window.SystemBarProperties = {
      statusBarColor: barColor,
    };
    // @ts-ignore
    windowClass.setWindowSystemBarProperties(sysBarProps, (err: BusinessError) => {
      let errCode: number = err.code;
      if (errCode) {
        console.error('Failed to set the system bar properties. Cause: ’ + JSON.stringify(err));
        return;
      }
      console.info(‘Succeeded in setting the system bar properties.’);
    });
  } catch (exception) {
    console.error(TAG, 'Failed to set the system bar properties. Cause: ’ + JSON.stringify(exception));
  }
});

2、升级到Beta5后上述方式失效，根据Beta5开发文档（https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-window-V5#setwindowsystembarproperties9），进行设置，在Beta5手机上仍然不生效。代码如下：

1. let windowClass: window.Window | undefined = undefined;
2. windowStage.getMainWindow((err: BusinessError, data) => {
3. const errCode: number = err.code;
4. if (errCode) {
5. console.error(Failed to obtain the main window. Cause code: ${err.code}, message: ${err.message});
6. return;
7. }
8. windowClass = data;
9. let SystemBarProperties: window.SystemBarProperties = {
10. statusBarColor: ‘#ff00ff’,
11. navigationBarColor: ‘#00ff00’,
12. //以下两个属性从API Version8开始支持
13. statusBarContentColor: ‘#ffffff’,
14. navigationBarContentColor: ‘#00ffff’
15. };
16. try {
17. let promise = windowClass.setWindowSystemBarProperties(SystemBarProperties);
18. promise.then(() => {
19. console.info(‘Succeeded in setting the system bar properties.’);
20. }).catch((err: BusinessError) => {
21. console.error(Failed to set the system bar properties. Cause code: ${err.code}, message: ${err.message});
22. });
23. } catch (exception) {
24. console.error(Failed to set the system bar properties. Cause code: ${exception.code}, message: ${exception.message});
25. }

有遇到的吗？
