Error C2664 cannot convert argument 1 from 'initializer list' to 'A &&' (compiles on VS2017 but not on VS2015)

Question

I have an issue with this code. I can compile it when I use Visual Studio 2017 (v141) platform toolset. However, when I switch to Visual Studio 2015 (v140), I hit this error:

Error C2664 'void std::vector<A,std::allocator<_Ty>>::push_back(const A &)': cannot convert argument 1 from 'initializer list' to 'A &&'

#include <vector>
#include <iostream>

struct A {
    double i;
    double j;
    int k = -1;
};
    
int main()
{
    std::vector<A> _object_rects;
    
    double i = 150;
    double j = 200;
    
    _object_rects.push_back({
        i,
        j });
    
    std::cout << "print structure: " << std::endl;
    
    std::cout << _object_rects[0].i << std::endl;
    std::cout << _object_rects[0].j << std::endl;
    std::cout << _object_rects[0].k << std::endl;
    
    system("pause");
    
    return 0;
}

Appreciate any help. Thanks.
