Re: [fxtf-drafts] [filter-effects] What should happen if filter and background-attachment fixed; applied to the same element?

But when you scroll and the background-attachment is fixed, then the element still moves out of the viewport. Only the image is fixed to the viewport, so there is the empty area above and below the viewport on that element and I think blur should be applied to that empty area, so the top blur area should move out from the viewport when you scroll down. 
Like on the right side of this example: https://jsfiddle.net/f1k94ce9/

I think this should be the desired behaviour: https://jsfiddle.net/3bdv532b/
(JavaScript changes the background-position on scroll, so it is a little bit laggy, but you can see the blur moving in and out at the top and at the very bottom of the image)
