Description Mihai Parparita 2010-09-17 17:25:38 PDT 
Test case: http://persistent.info/webkit/test-cases/animation-alternate.html

Expected result: gray box moves to the right and then back to the left.

Actual result: gray box moves to the right, jumps back to the starting point, and then moves again to the right.

This happens with both WebKit Window nightly builds and the Chromium canary channel. I haven't had a chance to narrow down the regression range, but it works as expected in the Safari 5.0.2 release but is broken as of r67637.  Chromium noticed this breakage with r67098 (see bug 45512), though I don't see how that would affect Windows only.
