[Ryosuke Niwa]

I have a fix for this. This test has the same issue as tiled-drawing/scrolling/fast-scroll-div-latched-mainframe-with-handler.html (bug 205364).

./Tools/Scripts/run-webkit-tests --debug LayoutTests/tiled-drawing/scrolling/fast-scroll-select-latched-mainframe.html --iterations 1000 --no-show-results --exit-after-n-failures=1 --force

runs fine with my fix.
