[webkit-dev] Rendering Help with MathML for mfenced

[Alex Milowski]

I found the fix.  I needed to call:

   open->updateBoxModelInfoFromStyle();
   close->updateBoxModelInfoFromStyle();

to update the box model from the style change for the open and
close fencing.  Then I needed to dirty the tree:

   markContainingBlocksForLayout();
   open->firstChild()->setNeedsLayoutAndPrefWidthsRecalc();
   close->firstChild()->setNeedsLayoutAndPrefWidthsRecalc();

It works perfectly!
