appium 版本：1.6.1
安卓版本：6.0
我的代码如下：

print(time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time())))
TouchAction(self.driver).long_press(element, None, None, 5000).perform()
print(time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time())))

执行没有报错，打印的时间也确实相差 5 秒，但是手机界面没有出现快捷操作（正常情况长按会出现快捷操作小图标），而是直接点进来，跳入新的界面。
appium 日志貌似也很正常，日志如下：

请问这个是什么原因呢
