WebKit exposes the accessible trees for munder/mover/munderover as

Role: AXMathRoleGroup
Subrole: AXMathUnderOver

and attributes AXMathBase, AXMathUnder and AXMathOver pointing to appropriate child accessible objects (base or under/over scripts).

Actual results:

1) a
2) a, with b underneath
3) a, with c underneath

Expected results:

1) a, with b underneath
2) a, with b above
3) a, with b underneath and c above.</pre>
