Почему лямбда, захваченная unique_ptr, не может использоваться в контейнере

Почему невозможно поместить лямбду, захваченную unique_ptr, в контейнер std::function? Это правильное стандартное поведение или проблема VC? Есть ли способ обойти это?

#include <memory>
#include <functional>
#include <vector>

using namespace std;

int main()
{
  unique_ptr<int> up{ new int{} };
  vector<function<void()>> cont;
  cont.push_back([up_{ move(up) }]() {});  // Error here
  return 0;
}
