I think the problem reduces to the fact that WebHTMLView ends up painting its
subviews into the window when it's sent a -cacheDisplayInRect:toBitmapImageRep:
message. You can see this by creating a trivial browser in Interface Builder
and adding a button that does something like
    NSRect frame = [webView frame];
    NSBitmapImageRep *rep = [webView
bitmapImageRepForCachingDisplayInRect:frame];
    [webView cacheDisplayInRect:frame toBitmapImageRep:rep];
Load http://www.nomoreboxes.com/wcstore/ into the WebView, turn on Quartz Debug
flashing and click the button. You'll see the iframes being painted into the
window.

I'm guessing that this has to do with WebHTMLView overriding private AppKit
methods.
