Description Alexey Proskuryakov 2015-08-24 16:40:54 PDT

Main frame scroll snap tests have become flaky after http://trac.webkit.org/projects/webkit/changeset/188793

Steps to reproduce:
1. Edit tiled-drawing/scrolling/scroll-snap/scroll-snap-mandatory-mainframe-vertical.html (this makes it 100% reproducible for me).
2. Add "document.body.offsetTopl" at the beginning on onLoad function.
3. Run the test.

What happens is that callAfterSCrollingCompletes callback is called before scrolling completes.
