Wrong equation for standard block in Unit 2 - ResNet

https://huggingface.co/learn/computer-vision-course/unit2/cnns/resnet#2-learning-residuals-and-gradient-flow

In the section describing Resnet Architecture, the equation for the standard block (without residuals) is given as
∂x/∂L = ∂F(x)/∂L * ∂F(x)/∂x

But shouldn't it be
∂L/∂x = ∂L/∂F(x) * ∂F(x)/∂x
