[Blindmath] MathML and VOiceOver?

[Bill Dengler]

The math is read twice, sometimes three times when say all is used.
The math should only be read once.
Unfortunately, I can’t give a very detailed explanation for what happens on Stackexchange. The page jumping issues are very random. It always occurs (it should never occur), but the location where the curser goes seems random. Sometimes to the beginning of the page, other times just seemingly any position.

What happens if you use VoiceOver’s navigation commands (Ctrl-Option-Left and Right-arrow) to read the text and the mathematical expressions? You should be able to interact with the mathematical expressions and then read them.
>> 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
