          REGRESSION: Status bar always shows cancelled opening the page

        * platform/network/mac/ResourceHandleMac.mm:
        (WebCore::ResourceHandle::~ResourceHandle): Removed call to cancel.
        Since the subresource owns the resource handle, there's no need to cancel.
        This arrangement is only temporary, anyway, since Maciej will soon change
        things so that the subresource loader uses the resource handle and the
        resource handle doesn't know anything about the subresource loader.
