mathml/opentype/horizontal.html is failing on GTK since r174540 <http://trac.webkit.org/r174540> Regressions: Unexpected text-only failures (1) mathml/opentype/horizontal.html [ Failure ] The diff is: https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/r174601%20%283403%29/mathml/opentype/horizontal-pretty-diff.html Maybe it needs just to be rebaselined? I'm asking because r174540 didn't touched or rebaselined this test for Mac or other port. So I'm not sure if this is a real failure or it just needs to be rebaselined. This is what the GTK MiniBrowser renders: http://people.igalia.com/clopez/opentype-horizontal.jpg

BTW, on https://trac.webkit.org/r174605 I rebaselined for the GTK port this other two tests mathml/opentype/munderover-window-resize.html mathml/opentype/opentype-stretchy-horizontal.html Since that both tests were also updated for the mac port on r174540, and the diffs where coherent (pixel sizes only) I guessed that rebaselining them is correct.

This is what the GTK MiniBrowser renders: http://people.igalia.com/clopez/opentype-horizontal.jpg I did not rebaseline them because they are excluded from the mac test suite. In the file LayoutTests/platform/mac/TestExpectations, these lines are there: webkit.org/b/72828 mathml/opentype/horizontal.html [ Failure ] webkit.org/b/72828 mathml/opentype/horizontal-munderover.html [ Failure ] # Missing references webkit.org/b/119038 mathml/presentation/mo-stretch.html [ Failure ] webkit.org/b/119038 mathml/presentation/roots.xhtml [ Failure ] So I think for GTK, it is safe to rebaseline all the MathML tests which are failing because of munderover object layout and which are expected to fail on Mac. For Mac we need to do the same but maybe when these tests are expected to succeed.

For Mac we need to do the same but maybe when these tests are expected to succeed. I have rebaselined the test for GTK on r174685 <http://trac.webkit.org/r174685> Thanks for your help. Closing the bug.
