No clear regression point, but this has become much more frequent about a week ago.
Comment 2 Alexey Proskuryakov 2017-03-29 13:20:28 PDT
Easily reproducible under CPU pressure:

run-webkit-tests -1 -v --no-build fast/images/reset-image-animation.html --repeat-each 1000 -f --child-processes=20
Comment 3 Alexey Proskuryakov 2017-03-29 17:35:26 PDT
r214450 had a fix to make the test not flaky, but it is still flaky.
Comment 4 Ryan Haddad 2017-04-04 18:00:27 PDT
Marked test as flaky in https://trac.webkit.org/r214921
