Contributed by Paul,
This is just a suggestion for people who want to adjust the
MathJax behavior to their need and do not want to reply on the
choices made in multi markdown. It is not completely satisfactory
but works. If you add anywhere in your document (top or bottom
being the most obvious) an explicit HTML header (example below) the
Marked will use the Mathjax behavior of your choice.
Of course do not use "Include MathJax from CDN" in the Preferences or you will get an unpredictable mixture of both the default behavior and yours.
Hope this helps
%%%% My headers Inserted at the bottom of my docs HTML header should be at the start of a new line of course
