CCControlButton touch priority bug or feature?

cocos2d-x C++
#1

I’ve found what calling method setDefaultTouchPriority on any ControlElement is not affecting on touch priority itself.
In the file CCControl.cpp we could find this code

//In the init method
m_nDefaultTouchPriority = 1;
this->setDefaultTouchPriority(m_nDefaultTouchPriority);

//And in the overrided registerWithTouchDispatcher method
CCDirector::sharedDirector()->getTouchDispatcher()->addTargetedDelegate(this, kCCMenuHandlerPriority, true);

So in any case we will set the priority of the control equals to 128. Why not doing like this?
<pre>
//In the init method
m_nDefaultTouchPriority = kCCMenuHandlerPriority;
this>setDefaultTouchPriority(m_nDefaultTouchPriority);

//And in the overrided registerWithTouchDispatcher method
CCDirector::sharedDirector()->getTouchDispatcher()->addTargetedDelegate(this, nDefaultTouchPriority, true);

This is not makes sense to me. If it is a bug i could create a pull request on github

Hello.

I confirm this bug.

BTW it may be worth to have a separate forum thread where it would place the potential bugs?
