In bug 113720, an attribute NSAccessibilityMathLineThicknessAttribute was added to AXMathFraction to help distinguishing fractions that have a bar or not.
Compare data:text/html,<math><mrow><mo>(</mo><mfrac><mi>a</mi><mi>p</mi></mfrac><mo>)</mo></mrow></math>
(https://en.wikipedia.org/wiki/Legendre_symbol)
with data:text/html,<math><mrow><mo>(</mo><mfrac linethickness="0px"><mi>n</mi><mi>k</mi></mfrac><mo>)</mo></mrow></math>
(https://en.wikipedia.org/wiki/Combination)
However, VoiceOver does not distinguish the two cases, it always read "fraction start ... over ... end of fraction".
I think it should instead read the one with linethickness="0px" as "fraction without bar start ... over ... end of fraction", "stack start ... over .. end of stack" or something similar.

The fix for this issue was needed outside the WebKit project, therefore this is being resolved as 'Moved'.
This should now be fixed in shipping software.
