Any chance we can find a way of covering this with a regression test?

I would probably put the definition inside the if statement.

We have still not figured out how to test scrollbar platform appearance in regression tests, but I absolutely think we need to figure out a way. These behaviors have a way of regressing quietly and we only notice after an all-too-long time. 

I need to think about how we could actually do this. ScrollAnimatorMac is the place in the code that can know if the right thing is happening, but it doesn't currently have any mechanism to share that information. If we can think of what to share it to, we might be able to figure out test infrastructure.

Okay!

Thanks Darin!
