Patch

I can't see the leak results from the above links. But I can see the following leak in recent build, so I'm assume the bug was reporting the same issue.

Leak: 0x1165e1df0  size=464  zone: DefaultMallocZone_0x105f89000        instance of 'WebCore::SVGShadowTreeRootElement', type C++, implemented in WebCore
