Current MathJax package strips SVG and PNG fonts, but there are cases when for some reason normal fonts are not shown.

In addition, having not SVG fonts but choosing SVG rendrer makes MathJax menu unavailable on the webpage without a clear fix (refreshing does not show any formulas at all).

One of the reasons for stripping PNG fonts was that they are copied to all folders in the documentation - this wastes gigabytes of space and has to be addressed.
