Having CSS "filter:blur(0)" on <iframe> makes scrollbar invisible

Reported by viller...@gmail.com, Aug 16 2017

I think this is really a paint issue. That said, I reproduced this in 60.0.3112.101 but could not in 62.0.3188.0 (ToT build).

viller239@gmail.com, could you try this in Canary channel and see if it still reproduces?

Looks like this works in 61 as well so given that's shipping in a week or two I don't think there's anything more to do here.
