Anyone else seeing | symbol appear AFTER math stuff?

I didn't use to have this problem but it seems like | started appearing after math stuff.  (I use PGML if that matters.)

I've attached a screenshot of the problem.  Here's the
source for the problem....

Context("Numeric") ; Context()->flags->set(tolerance => 0.01);

BEGIN_PGML
Calculate [\int_{-3}^{3} \sqrt{9 - x^2} dx].

Hint: What is the shape of the corresponding area?

Apparently this is a bug in MathJax that was recently fixed.
