The monk does not handle math correctly

[HoldYourWaffle]

The monk currently identifies answers based on the 'orphan text' inside an input's label, but "math text" is written in deeply nested "MathJax" structures.

An example of such a structure:

<label for="q50348:19_answer1" class="ml-1">
   <span class="answernumber">b. </span>
   <span class="filter_mathjaxloader_equation">
