The following code example on meta renders without any syntax highlighting, despite a syntax highlighting directive:
from math import sqrt class Triangle: def hypotenuse(self): # equation 2 return sqrt(self.a**2 + self.b**2)
(The directive used here is
<!-- language: lang-py -->.)
On mainsite it renders fairly prettily:
The lack of syntax highlighting impacts the readability of meta documentation, such as in this Mathjax documentation here which includes the above Python block — as a screenshot, not as an actual code block, so as to get the code syntax highlighted properly to demonstrate what this would look like mainsite.
