fast/block/float/floats-with-margin-should-not-wrap.html was caused by this change the other tests though fail without the patch as well. Will fix the new test and re-land.
Comment 6 Stephanie Lewis 2012-05-24 14:23:45 PDT
Can you explain what you mean by the other tests are failing anyway?  I verified on my personal machine that the tests starting failing with 118297.  The tests stopped failing on the bots after the rollout.

* +fast/frames/flattening/iframe-tiny.html   This test had just became flaky and is not related.

I fail exactly the same set of tests with and without the patch. I tried on two different (mac) machines and got the same results on both.
Comment 8 Emil A Eklund 2012-05-24 14:35:30 PDT
Argh, ignore my previous comment.

There are certain tests that will need to have the text expectations rebaselined on some versions of mac, basically having the margin rebaselines from r115573 reverted. Sadly I forgot to include those baselines in the patch, which caused this confusion. I do apologize about that.
Comment 9 Emil A Eklund 2012-05-24 14:38:21 PDT
And just for the record, rolling the change back was the right thing to do regardless as the new test was failing.
