The new tests added under imported/mozilla/css-animations and imported/mozilla/css-transitions are mostly failing reliably, flaky or timing out.
Skipped imported/mozilla/css-animations/test_keyframeeffect-getkeyframes.html as the test is crashing consistently and may cause instability with other tests.

Matt, what was the crash? Maybe it was the ASSERT that caused https://bugs.webkit.org/show_bug.cgi?id=184077 to be rolled out. It has now been fixed, and maybe we should look into this again.
The Mozilla bugs have been removed for https://bugs.webkit.org/show_bug.cgi?id=203291 in r251536.
