Description Truitt Savell 2020-02-05 11:21:47 PST 
imported/w3c/web-platform-tests/web-animations/timing-model/animations/finishing-an-animation.html

This test began failing with the changes in https://trac.webkit.org/changeset/255821/webkit
I was able to reproduce this locally by simply running the test in iterations. I bisected it down to r255821.
This is a flaky failure and it seems this test is randomly getting an additional console message.
