Why does this return a raw pointer?

It calls a method that returns a PassRefPtr, and one of the callers then wraps
it back into a PassRefPtr. The other caller presumably doesn't care whether it's
a raw pointer or a PassRefPtr, but it seems like there's no problem with it
being a PassRefPtr?

Done.
