--- Comment #3 from Frédéric Wang (:fredw) <fred.wang at free.fr> ---
Just took a quick look now, it seems enough to call updateScrollInfoAfterLayout() in layoutBlock like what is done in RenderBlock::simplifiedLayout().

diff --git a/Source/WebCore/rendering/mathml/RenderMathMLBlock.cpp b/Source/WebCore/rendering/mathml/RenderMathMLBlock.cpp

     repainter.repaintAfterLayout();

+    updateScrollInfoAfterLayout();
+
     clearNeedsLayout();
 }

However, we need to do that in all implementations and add test for each case. Would be similar to bug 178865 I guess.
