fast/forms/basic-input.html has different results on Windows than on Mac. This has been true ever since the test was added in r48699. I was pretty sure that our form control metrics were the same between Windows and Mac under DRT, so this seems like a bug.
Landed an expected failure result. Committed r48975: <http://trac.webkit.org/changeset/48975>
