--- Comment #1 from Frédéric Wang (:fredw) <fred.wang at free.fr> ---
Just reading the code, I see that RenderMathMLRow::layoutRowItems does not call layoutIfNeeded for OutOfFlowPositioned children. This logic was copied from the flexbox code but I'm not sure how RenderFlexibleBox::layoutBlock ensures that clearNeedsLayout() won't ASSERT. I wonder whether we could just remove that OutOfFlowPositioned logic for MathML.

@javi: Any idea?
