cocos2dx 3.6 Sequence cannot stopAction bug

cocos2d-x C++
1

we try to use stopAction to control the Sequence action, but we found it’s not work.
Test code like below:

m_testAction = this->runAction(Sequence::create(CallFunc::create(CC_CALLBACK_0(MainLayer::test1, this)),
                                                DelayTime::create(2),
                                                CallFunc::create(CC_CALLBACK_0(MainLayer::test2, this)),
                                                CallFunc::create(CC_CALLBACK_0(MainLayer::test3, this)),
                                                NULL));

void MainLayer::test1()
{
    cout << "test1 done" << endl;
}
void MainLayer::test2()
{
    cout << "test2 done" << endl;
    this->stopAction(m_testAction);
}
void MainLayer::test3()
{
    cout << "test3 done" << endl;
}

The expect output should be:
test1 done
test2 done

But we got:
test1 done
test2 done
test3 done

It’s become normal when we comment the line of DelayTime::create(2).
Does it a bug of cocos2dx 3.6?
