The code with a problem is:

typedef struct {
  int a;
} struct_t;

int func(int a) {
  return a;
}

void test(void) {
  struct_t s;
  struct_t *ptr;

  func(s.a);
  func(ptr->a);

  switch(1) {
    case 1:
      func(s.a);
      func(ptr->a);
  }
}

It looks like:

It should look like:

Confirmed with with scope inspector that inside the switch they're being scoped as keyword.operator.c not dot/pointer access. Works fine outside a function call and confirmed to work in .cpp files.
