I might like to see the changelog describe why preserve-3d and reflection layers hit this.

typo this->these

This kind of thing is supposed to work without the get().

> Source/WebCore/platform/graphics/ca/mac/PlatformCALayerMac.mm:341

Ditto.

> Source/WebCore/platform/graphics/ca/mac/PlatformCALayerMac.mm:349
> +    ASSERT(m_layer.get() != layer->m_layer.get());

Again.
