Inconsistent scope for pointers in parameter lists in C++

The code with a problem is:

struct s
{
    int func(char *s);
    char *s;
};

It looks like:

Default dark theme. Scope for "*" in the parameter is storage.modifier.pointer.cpp.

It should look like:

Scope for all other cases is keyword.operator.cpp (and for params in C). I don't know which case is correct, but the inconsistency seems incorrect.
