This is caused by this code in JSDOMBinding.h:

        // If a wrapper is the last reference to an image or script element
        // that is loading but not in the document, the wrapper is observable
        // because it is the only thing keeping the image element alive, and if
        // the image element is destroyed, its load event will not fire.
        // FIXME: The DOM should manage this issue without the help of JavaScript wrappers.
        if (node->hasTagName(imgTag) && !static_cast<HTMLImageElement*>(node)->haveFiredLoadEvent())
            return true;
        if (node->hasTagName(scriptTag) && !static_cast<HTMLScriptElement*>(node)->haveFiredLoadEvent())
            return true;
#if ENABLE(VIDEO)
        if (node->hasTagName(audioTag) && !static_cast<HTMLAudioElement*>(node)->paused())
            return true;
#endif
