        LayoutTests/animations/play-state.html and LayoutTests/transitions/cancel-transition.html are still flaky
        https://bugs.webkit.org/show_bug.cgi?id=33748

        * animations/play-state-expected.txt:
        * animations/play-state.html:
        Undo my previous change of decreasing the length of the test. I think that made it more flaky.
        Also increase the tolerance.

        * transitions/cancel-transition.html:
        Undo my previous change of moving the setTimeout. It was correct where it was.
        Added a comment to make it more clear. The tolerances were increased since then though,
        so this test should no longer be flaky after this.
