> Do any of the other layout state flags need to be reset as well?  E.g., m_hasPendingPostLayoutTasks seems like it might fall into the same bad state.

I'm not sure, maybe someone more familiar with WebCore layout can answer that.  The issue here is that m_firstVisuallyNonEmptyLayoutCallbackPending is only set once, in FrameView's constructor.  I guess the assumption was that page loads correspond to new FrameViews.  This assumption is broken when a page is restored from the b/f cache.
