Wrong result of expression using selfadjointView on 1D matrix

https://godbolt.org/z/q6vrr57qM

template<int N>
using MatrixNf = Eigen::Matrix<float, N, N>;

int main() {
    const MatrixNf<1> m = MatrixNf<1>::Constant(2);
    const Eigen::Vector3f v = Eigen::Vector3f::Constant(3);
    const MatrixNf<1> m_selfadjoint = m.selfadjointView<Eigen::Lower>();

    // Expected these outputs to be equal
    std::cout << v * m_selfadjoint * v.transpose() << "\n\n";
    std::cout << v * m.selfadjointView<Eigen::Lower>() * v.transpose() << "\n\n";
}

Output:

18 18 18
18 18 18
18 18 18

18 18 18
