MathJax Output Format in LMS

Issue: 
MathJax expressions were not rendering properly in the drop-down menu. 

Reason: 
MathJax SVG configurations do not work properly in case of a drop-down menu.

Solution:
The output format for MathJax expressions changed from SVG to HTML to allow the MathJax rendering in the drop-down menu as well. 

Become oep2 compliant.
