           Summary: load event can fire prematurely for frameless documents
           Product: WebKit
           Version: 522+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Page Loading
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: ggaren at apple.com


FrameLoader tracks loading progress. Without a FrameLoader, a Document doesn't
know whether loading is in progress. Therefore, a Document might end up
dispatching the load event too early.

This is the responsible code, in Document.cpp:

void Document::close()
{
    Frame* frame = this->frame();
    if (frame) {
        // This code calls implicitClose() if all loading has completed.
        FrameLoader* frameLoader = frame->loader();
        frameLoader->endIfNotLoadingMainResource();
        frameLoader->checkCompleted();
    } else {
        // Because we have no frame, we don't know if all loading has
completed,
        // so we just call implicitClose() immediately. FIXME: This might fire
        // the load event prematurely.
        implicitClose();
    }
}

I don't know if this is a real-world problem or not.
