So I actually found out this already exists in
Scrollbar::shouldParticipateInHitTesting for Mac overlays but it requires a
little more plumbing that I did in https://codereview.chromium.org/2467693002/.
So leave this in but add a TODO(bokan) to remove and I'll remove it once my
patch lands and we can use that instead.
