With the new MathML layout, the RenderMathMLMenclose class probably needs to be rewritten too to implement computePreferredLogicalWidths, layoutBlock, firstBaseLine etc since (because of the notations) the metrics and child placement do not really exactly correspond to RenderMathMLRow. I suspect the list of notations could also be more efficiently managed with an integer m_Notations and corresponding bit mask for each notation as done in Gecko. Last but not least, we should avoid creating anonymous RenderMathMLSquareRoot.
