Eric,

Thanks for reporting this very interesting error with latexit.js. The error seems to be caused when we deliver scalable svg graphic of the equation, which for some reason doesn't translate this one particular equation 'ax>b'. Interestingly any other variant seems to work.

A simple work around is to add a space after the 'x' and before '>', i.e.

$ax >b$

Once this is fixed you shouldn't need to change anything yourself.
