issue with role="presentation"

[WayneEDick]

Issue Summary

An accessibility problem with MathJax

I am taking an excellent class: Algebraic Calculus One on Open Learning.

When I use read with VoiceOver I get "presentation" read at the end of expressions.

<span class="MathJax" id="MathJax-Element-19-Frame" tabindex="0" style="text-align: center; position: relative;" data-mathml="

... math expression ... " role="presentation"> ........ This is the problem. ... Stuff ...

I see no reason why role= "presentation" is needed.

When you are trying to absorb a mathematical concept the statement "presentation" occuring at what seems to be random places really breaks concentration.

Is there a way around that?

Sincerely, Wayne

PS: You cannot turn off role in the verbosity.

Steps to Reproduce

1. This is the first step

This is a bug because... People who want to read the material cannot concentrate while reading mathematics.

This role is being added by the AssistiveMML extension when it adds the hidden MathML, and apparently stems from issue #1235.

If you switch to NativeMML output, that will insert MathML and disable the AssistiveMML extension. Does that help your situation?
