test case

WebHTMLView attempts to scale the document down a little if it sees that the last page is very small, in order to avoid orphans. This got broken with r67771, because PrintContext::computePageRectsWithPageSizeInternal always returns all pages with the same size now.

I tried to fix this by undoing the part of PrintContext change that changed the height of the last page, but that created a bigger problem - css-page-break is no longer respected properly, as computePageRectsWithPageSizeInternal() is called after layout.
