The painting code is invoked by -[WebHTMLView
_recursiveDisplayAllDirtyWithLockFocus:visRect:] after it calls -[WebHTMLView
_web_layoutIfNeededRecursive:testDirtyRect:].

> Why doesn't that code trigger a layout if it's pending?

Calling _web_layoutIfNeededRecursive:testDirtyRect: is doing just that.

I think "the real problem" here is that there is a method that promises to do
layout but fails to deliver. That method is -[WebHTMLView
layoutToMinimumPageWidth:maximumPageWidth:adjustingViewSize:], and the proposed
patch ensures that it will always do what it says it does.
