This is affecting EWS, so we need to identify the culprit.

I see the same kind of failure on this test happen before the grid change, but with dramatically lower frequency. Something definitely changed there. Reproducing locally may be the best next step.

I don't believe this is related with my patch r228095. The only change it has on transitions/animations code is to add a new property (row-gap) as animatable: https://trac.webkit.org/changeset/228095/webkit#file56
