Hi,

I am revising my lecture on automatic differentiation and I have noticed that Documenter has started to break vertical line that I insert as

```
``J_i = \left.\frac{f_i}{\partial y_i}\right|_{y_i^0} ``
```

Does any has an idea, what am I doing wrong or how can I fix this? In latex, I was always type it this way.

Thanks for help in advance.

Tomas
