REGRESSION (r117815) fast/css/zoom-in-length-round-trip.html fails on Mac bots Link to change: http://trac.webkit.org/changeset/117815 Link to example of failure: http://build.webkit.org/results/Lion%20Release%20(Tests)/r117988%20(8548)/results.html 117815 purported to be only about enabling a feature on Chromium, so it seems odd it could have caused this. But it never failed up to and including 117813, then has been failing started in 117815. 117814 cannot possibly have affected Mac as it only touched a Chromium.cpp file - (http://trac.webkit.org/changeset/117814) - so 117815 must be it.

It's possible, but it would have come from an earlier change in teh subpixel change I think.

(In reply to comment #2) > It's possible, but it would have come from an earlier change in teh subpixel change I think. I'm having a hard time grok'ing this sentence. All I know is that from 117813 back the test was fine.

The numbers being returned are correct, it looks like a test issue.
