> As far as how to solve this regression with Safari RSS's sidebar, using requestAnimationFrame (http://webstuff.nfshost.com/anim-timing/Overview.html) may be an option. That way you can invoke the custom sidebar sizing/moving logic before painting. 

So here's something I don't get. Why is running a requestAnimationFrame script callback before painting ok, but invoking the scroll event before painting would, per comment #18, be bad? If requestAnimationFrame is an acceptable API, then surely the right long-term fix is Hyatt's suggestion from comment #13.
