导航栏设置问题：设置状态栏，底部导航栏时感觉底部导航栏设置隐藏无效

let names: Array<'status' | 'navigation'> = [];  
try {  
  windowClass.setWindowSystemBarEnable(names, (err: BusinessError) => {  
    const errCode: number = err.code;  
    if (errCode) {  
      console.error('Failed to set the system bar to be invisible. Cause:' + JSON.stringify(err));  
      return;  
    }  
    console.info('Succeeded in setting the system bar to be invisible.');  
  });  
} catch (exception) {  
  console.error('Failed to set the system bar to be invisible. Cause:' + JSON.stringify(exception));  
}
