  fixed-z-index-blend.html: scrollBy before the requestAnimationFrame callbacks
https://bugs.webkit.org/show_bug.cgi?id=314216
rdar://176378344

Reviewed by Simon Fraser.

The two requestAnimationFrame (rAF) callbacks ran before any scroll,
so the snapshot raced with the scroll-induced layer commit. Move
scrollBy to script execution time so the first frame is already at the
target, and let the rAFs settle two render updates before
takeScreenshot.
