Ouch. I think that -webkit-linebox-contain maybe doesn't work on the EFL port? Maybe the functions it calls to get glyph metrics don't work on that port? Or maybe the STIX fonts have problems on EFL?

Note that the old results on EFL may have been much worse than you see in the *-expected.png results here. People using MathML in general (e.g. in Firefox) are expected to download the STIX fonts so they can see various mathematical symbols. Apparently this was Alex Milowski's intention for WebKit MathML as well. Anyway, the STIX fonts didn't used to be enabled in the layout tests. So the old test results were showing better formatting than people were actually seeing, because the STIX fonts have large ascents and descents that were screwing up the old formatting in real use, even in the Apple/Mac port.

Thanks for uploading your attached test results. I will look into this further.
