Incorrect highlighting of explicit base member specification

The following code is not parsed correctly by the syntax highlighter.

class Base
{
  int member;
};

class Derived : public Base
{
public:
  Derived()
  {
    this->Base::member = 10;
  }
};

Here, in the Base::member initialization, Base is highlighted as if it was a data member of the class and ::member is black (I assume, it is not recognized at all). The parser should first recognize the :: operator, which results in Base being a class name and member being the class member.
