List of unsupported features
IAccessible methods that we don't currently support:
- Visual Basic (IDispatch) bindings for IAccessible.
- Directional navigation via accNavigate()
- Scroll bars as IAccessible objects, although we do support EVENT_SCROLLINGEND when scrolling stops, ISimpleDOMNode::ScrollTo() and IA2 scrolling methods
- STATE_MARQUEED. If that state is present it actually indicates "CHECKABLE" in Mozilla.
- See below for the complete list of roles and notes about what we support
