WebKit exposes the attribute AXMathLineThickness that allows to present the thickness of the fraction bar. I'm not sure how it is used by VoiceOver, but it's at least important to e.g. distinguish between combination (linethickness="0px") or Legendre symbol (with default linethickness).

Although WebKit exposes this attribute, it does not seem to be used by VoiceOver (https://bugs.webkit.org/show_bug.cgi?id=146454) so we can not really test it. Also, the accessibility inspector does not seem to display all attributes for me, so I add to test the code using some debug logging...
