I'm going to land bug 1498639 without the assertion that we always find the node we're scrolling relative to, otherwise we hit that assertion in layout/reftests/transform-3d/perspective-origin-4a.html.

Apparently we can scroll across reference frames, yay, but this is a decent change and I don't really think we should land it as part of that bug, since it's a bit more risky.

So I have a patch but I haven't been able to find a test-case where it matters... Matt, do you know when can this happen?
