Description Tim Horton 2013-10-04 11:37:05 PDT 
http://trac.webkit.org/changeset/115751 made forceRepaintAsync use dispatchAfterEnsuringUpdatedScrollPosition. However, in https://bugs.webkit.org/show_bug.cgi?id=122299 (and in experiments with turning on tiled drawing for all tests), we've seen cases where even after waiting for a force repaint to finish, the main thread's notion of the scroll position can be wrong.

This probably blocks turning on threaded scrolling for all of the tests.
