onTouchMoved() repeatedly called when there is no movement occurring

Issue found with cocos2d-x 3.71 running on Android 5.1.1 (lollipop) . When a touch-and-hold (with no movement) is executed, onTouchMoved() is continuously called until the touch is released. This has been confirmed by a second party on Lollipop with cocos2d-x 3.8, but they said it does not occur on 4.4.2 KitKat.

Add the following class (testNode.h) as a child of the HelloWorldScene example and run on Android 5.1.1 to recreate the problem:

testNode.h:

#pragma once
#include "cocos2d.h"

class testNode : public cocos2d::Node
{
public:
    testNode() {}
    ~testNode() {}
    CREATE_FUNC(testNode);

    virtual bool init();
    virtual void update(float dt);
    bool onTouchBegan(cocos2d::Touch*, cocos2d::Event*);
    void onTouchMoved(cocos2d::Touch*, cocos2d::Event*);
    void onTouchEnded(cocos2d::Touch*, cocos2d::Event*);
    void onTouchCancelled(cocos2d::Touch*, cocos2d::Event*);

private:
    cocos2d::DrawNode* d;
    int id;
    bool touchIsDown;
    float touchTime;
    cocos2d::Label *messageLabel;
    cocos2d::Vec2 center;
};

        }
    }
}

bool testNode::onTouchBegan(Touch* touch, Event* event)
{
    Vec2 touchPoint = touch->getLocation();
    float startDistFromCenter = center.getDistance(touchPoint);
    touchTime = 0.0f;
    // Handle touch only if inside the radius of the circle
    if (startDistFromCenter <= 50)
