Crash when meeting wrong expression

[ABackerNINI]

This extension is a good idea, but there is a small problem.

I copied the math code log(sinf(atan2f(hypot(abs(a + b), abs(c)), d + f)). in your readme, which is a wrong expression, there should be 3 ')'s at the end. And when I hover my mouse on it, it shows "loading". The extension seems getting into an endless loop and prevents me editing my files.
