[C++] using a operator() of a templated class leads to wrong syntax highlighting results

This piece of code:

template <typename T>
struct bar{
    int operator()(char x){
        return 0;
    }
};

struct foo:public bar<int>{
    using bar<int>::operator();
};

seems to produce wrong syntax highlighting results for ollowing class/struct declarations/definations and endif macros. On my workspace(VSCode 0.10.8 with Dark+ (default dark) color scheme) it behaves like this:

Other macros including define, include, if and ifdef are not affected though.
