[Blindmath] MathML and VOiceOver?

Hello,
I’m running OS X 10.11.2.
It seems that when VoiceOver encounters MathMl on a page, say all behaves unexpectedly.
Steps to reproduce:
1. GO to http://enwp.org/special:preferences
2. Click the appearance tab.
3. In The math section, select "MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools)”
4. Click save.
5. Go to http://enwp.org/ackermann_function
Perform a say all.
On other sites, MathML is not focusable; when VO encounters it the focus jumps to somewhere else on the page, making it difficult to read (or skip) the math. For example: http://math.stackexchange.com/questions/253997/how-to-find-the-sum-of-an-alternating-series
Any ideas?

Thanks,
Bill
