            Bug ID: 159205
           Summary: AX: Remove dead code for RenderText and
                    RenderMathMLOperator in
                    AccessibilityRenderObject::textUnderElement
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All

            Status: NEW

RenderMathMLOperator used to destroy its descendants and to replace them with an anonymous text node wrapped inside anonymous blocks. After r202420, it just behaves as any other token elements. Hence the code in AccessibilityRenderObject::textUnderElement to handle this specific render tree structure is never executed and can be safely removed.
