Tangential to your issue, but nota bene: instead of $...$ for inline
math, ConTeXt lets you use \math{...} or \m{...}. Which is a bit more
explicit, and can be easier to debug. You might prefer it.

For display math, you really should use \startformula...\stopformula
if you aren’t using it already, because $$...$$ doesn't space
correctly. (Says the wiki. I don’t know it’s still true.)

Cheers,
Sietse
