Marked test as flaky in https://trac.webkit.org/r227255
I'm working on a series of patches that will eventually make this WPT test have a 100% pass rate and not be flaky anymore. This should all land within the week.
The test has since moved to imported/w3c/web-platform-tests/web-animations/timing-model/animation-effects/current-iteration.html and passes reliably.
