Additional context

class base {
  // I'm comment
  virtual void foo() {}
};
class derive : public base {
  void foo() {}
};

As we often write comments on base class's (pure) virtual methods instead of repeating them on every derived classes, we hope these information could be passed to derived class when we hover the cursor on the method. Just like clion does like the following. It explicitly tells that the comment comes from base class, which will be very nice to readers.

@baiwfg2 I filed a feature request on VS at https://developercommunity.visualstudio.com/idea/965067/c-intellisense-show-base-class-method-comments-for.html . You could upvote that.

I think our implementations are somewhat divergent, but I think we plan to share more eventually, so if VS implements it then we may also get it.
