The test is also failing sometimes https://build-safari.apple.com/results/Trunk%20Syrah%20Production%20WK1%20Tests/r181656_70319%20(18656)/animations/trigger-container-scroll-simple-diff.txt
This is a new test from http://trac.webkit.org/changeset/181655
Test should be passing now. I need to work out the ASSERT.
Skipped in https://trac.webkit.org/r181749
