Shorthand double-argument commands are misinterpreted

[ShawElA]

When using shorthand forms like \frac12 inside other commands (e.g. \boxed{\frac12}), the plugin incorrectly treats them as single-argument commands, formatting it as \boxed{\frac{12}} instead of the correct \boxed{\frac{1}{2}}.

\boxed was not a command I was familiar with. It needs to be added to the list of amsmath macros with an inMathMode: true option. Then it should work.

@siefkenj Thanks for the prompt response! I wanted to highlight that this appears to be a broader parsing issue with shorthand double-argument commands when they're nested within any command context.

For example:

• \frac{\frac12}{a} gets misformatted as \frac{\frac{12}}{a} instead of \frac{\frac{1}{2}}{a}
• Similarly, \sqrt{\frac12} would become \sqrt{\frac{12}}

This suggests the parser needs special handling for shorthand fractions (\frac12, \xfrac34, etc.) regardless of their parent command context, not just specific commands like \boxed. The current behavior seems to treat them as single-argument fractions in nested positions.

I have just run into this issue too:

\int_{\frac12x}

incorrectly becomes:

\int_{\frac{12x}}

instead of:

\int_{\frac{1}{2}x}

and causes the MathJax error:

Extra close brace or missing open brace
