Was able to reproduce to failure using the following test:

run-webkit-test imported/w3c/web-platform-tests/css/css-transitions/properties-value-003.html --iterations 1000 -f

Revision r275227 was not available to me. The history is pretty clear that's where it started, and I did produce the failure at r275228, but not at r275226.

I just noticed that. I'll be looking at this tomorrow.

[Antoine Quint]

This actually just needs a rebaseline, this test now fails later than it used to, so it is actually a progression.

[Robert Jenner]

Removed all test expectations here because this was causing it not to be flagged by EWS:
https://trac.webkit.org/changeset/275309/webkit

Rebaselined test here: 

https://trac.webkit.org/changeset/275311/webkit

I hope I did this correctly, this is only the second time I've done this.
