"AXMathRootRadicand [should] return an array of elements. This would cover the root of any index and possible variants like the root of a complex number or even future tweaks to the spec." This change in WebKit will require a counterpart change in VoiceOver.

Testcase:
data:text/html,<math><msqrt><mi>x</mi><mi>y</mi></msqrt></math>

Accessible tree exposed by Safari:
Role: AXGroup
Subrole: AXMathSquareRoot
MathRootRadicand: pointer to child "x"
accessibilityChildren: 3 items
  0 AXStaticText (radical symbol)
  1 AXMathIdentifier (x)
  2 AXMathIdentifier (y)
