The following markup:
  <table>
    <tr valign="top">
      <td>
        <img style="height:1.2em" width="1">
        one <span>two</span> three <span>four</span> five
      </td>
    </tr>
  </table>
(live at http://persistent.info/webkit/test-cases/text-baseline.html - this is a reduction of a Google Groups UI page)

Results in "two" and "four" appearing lower than "one",  "three" and "five" (see screenshot). This happens in a ToT build (r88490) but does not in Safari 5.0 Firefox 4.0 or Opera 10.63. I will try to find a narrower regression range.

This appears to be rendering correctly at r78794 and incorrectly at r79249.

[Mihai Parparita]

Using Chromium archived builds, I was able to narrow down the regression to be between r78845 and r79002. The main text/rendering change in this range is http://trac.webkit.org/changeset/78846/, which has caused other regressions too, so I'm declaring it the smoking gun.

[Brent Fulgham]

Safari, Chrome, and Firefox all agree on rendering for this test case. I don't believe there is any remaining compatibility issue.
