Q_PROPERTY refactor uses wrong case

I have been enjoying the use of the Q_PROPERTY() code completion and refactoring for quite a while, but ran into an issue with 4.9.0. 

When I attempt to generate a Q_PROPERTY() in 4.9.0 it auto completes the Q_PROPERTY() with the proper cases based on the initial property name specified:

Q_PROPERTY(bool testPropName READ testPropName WRITE setTestPropName NOTIFY testPropNameChanged)

However, then when I right click and issue a "Refactor - Generate Missing Q_PROPERTY Members" ... it results in this:

bool testPropName() const 
{ 
    return m_testPropName; 
}

void settestPropName(bool testPropName) 
{ 
    if (m_testPropName == testPropName) 
        return; 

    m_testPropName = testPropName;       
    emit testPropNameChanged(m_testPropName); 
}

void testPropNameChanged(bool testPropName);

bool m_testPropName;

 You can see that "setTestPropName" somehow gets generated as "settestPropName". This worked as expected before updating, so don't think it's something with my build.
