[BlindMath] Screen reader extension for viewing math content in LaTeX and AsciiMath notations as MathML

[Alastair Irving]

Hi

I see what the problem is.  There's a bug in MathJax 3.1.1 with commands 
followed by a space (\sqrt2 works but \sqrt 2 doesn't). From the Github 
releases page:

"MathJax v3.1.2

Hot fix to correct regression introduced in v3.1.1 that caused control 
sequences followed by spaces to not be recognized."

If you upgrade the addon to use the new version I think my problems will 
all be solved.

Best wishes

Alastair
