           Summary: Page::pageCount() is inaccurate when we allow the
                    first paint in App Mode
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Keywords: InRadar
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: bdakin at apple.com


Page::pageCount() is inaccurate when we allow the first paint in App Mode, which happens when Document::setVisualUpdatesAllowed(true) is called. It should be accurate.

After layout is updated, the page count should be accurate, but it is not for paginated content that contains images because auto-height images are given a layout height of 0 after the first pass. They require a second pass to get the right height. They shouldn't.
