Physics \eval with only the 2nd argument

[rudolf-adamkovic]

The following renders correctly in LaTeX:

\pdv{x} x + 5 \eval_{y = 5}

With MathJax, it fails with:

Missing argument for \eval

The workaround for MathJax is to add an empty {}:

\pdv{x} x + 5 \eval{}_{y = 5}

The workaround should not be necessary.

Thank you for the report. I will look into fixing it.
