Should I go ahead with above modified function name or modify it to
inheritsNoneRole?

Since presentation would be deprecated.

     LayoutRect computeElementRect() const;
     VisibleSelection selection() const;
     int indexForVisiblePosition(const VisiblePosition&) const;
     void accessibilityChildrenFromAttribute(QualifiedName attr, AccessibilityChildrenVector&) const;
