Return a `shared_ptr<const ELEMENT_TYPE>` that shares ownership with an existing `shared_ptr` object that managed this object, and throw a `std::bad_weak_ptr` exception if there is no `shared_ptr` currently managing this object. If multiple groups of `shared_ptr`s are managing this object, the returned `shared_ptr` will share ownership with the group that first managed this object.
