StyleResolver::styleForDocument requires a 2-pass style recalc for correctness?

http://trac.webkit.org/browser/trunk/Source/WebCore/css/StyleResolver.cpp#L853

Maybe I'm reading it wrong.  But it appears that in order to get the correct styles for a document, we need to do a two-pass style recalc?

Elliot ran into this while trying to remove the full-document forced style recalcs which happen at every </style> in a document due to Document::didRemoveAllPendingStylesheet():
