LaTeX not being rendered correctly for math line of documentation in Box example

Line 360 in b588680

# \overline{\text{state\_now}} = \frac{\partial \text{out\_now}}{\partial \text{state\_now}}\right|_\text{state\_now} \overline{\text{out\_now} + \frac{\partial \text{out\_old}}{\partial \text{state\_now}}\right|_\text{state\_now} \overline{\text{out\_old}

is not rendered in Chrome or Firefox, and inspecting the code in Overleaf I see that there is use of \right| without a corresponding left call. I assume that this is intended as math notation for "restricted to". Looking at some search results, this requires a `\left.\ to match.

Could someone please confirm that the rendering is broken? Or does this work for some LaTex interpreter?
Thanks!

Modified code now reads

\overline{\text{state_now}} = \left.\frac{\partial \text{out_now}}{\partial \text{state_now}}\right|_\text{state_now} \overline{\text{out_now}} + \left.\frac{\partial \text{out_old}}{\partial \text{state_now}}\right|_\text{state_now} \overline{\text{out_old}}

and renders as

Can someone confirm that this is the intended rendering? Thanks! @vchuravy @swilliamson7 @just-walk
