Exposes the children of math regions.

ARIA Implementation Guide 1.0 says that math should be mapped to ROLE_SYSTEM_EQUATION but we omitted to expose its children.
Mac works fine ones AX_ROLE_MATH is removed from the list of leaf objects.
Also checked with Safari and it does expose the children of role="math".

Voiceover reads the text inside the math role. Jaws will not read text inside the math role unless I think it is MathML. NVDA should only read content if Math Player is installed and the content can be consumed by Math Player.
So, I believe that I did as much as I can do for now. We need to talk to figure out if we need to reach out to the screen reader vendors on Windows and if we can do anything further on our side.
