Latex is not evaluated if it is used in correct answer

[payenda]

@fpcorso
When I want to include Latex in correct answer, the plugin does not score that question. If Latex is used in question itself and in wrong answers but not in correct answer, the plugin evaluates and gives correct score but when I must use Latex for correct answer, the plugin does not evaluate that question.

The Plugin does not render Latex in result pages and I think it can not detect Latex to evaluate it. If rendering Latex is enabled for result pages maybe this problem will be solved.

I found a workaround replacing \ by \
BUT : when reediting the question, \ somtimes become \, and amp; have to be removed !

Since the last update (7.1.6) all \ characters are removed from the user's answers (but the latex formulas appear correctly in the choices) and correct users's choices are considered falses.
Using \ no longer solves the problem.

For example, in 'vertical multiple choice', the choice $$r=\frac{v}{\omega}$$ is correctly shown in the question :

But in the user's answer, it becomes : r=fracvomega

Thank you in advance for your help
