Description Frédéric Wang (:fredw) 2016-06-28 02:25:42 PDT
The test mathml/presentation/scripts-subsup.html is supposed to check the rendering of subsup scripts. However, the MathML 3 recommendation does not specify precisely how to implement these scripted elements so the test is not really accurate / reliable. Currently it is failing on most platforms:

LayoutTests$ find -type f -name TestExpectations | xargs grep scripts-subsup.html
./platform/ios-simulator/TestExpectations:mathml/presentation/scripts-subsup.html [ Pass ImageOnlyFailure ]
./platform/gtk/TestExpectations:webkit.org/b/142289 mathml/presentation/scripts-subsup.html [ ImageOnlyFailure ]
./platform/ios-simulator-wk1/TestExpectations:mathml/presentation/scripts-subsup.html [ ImageOnlyFailure ]
./platform/mac/TestExpectations:mathml/presentation/scripts-subsup.html [ Pass ImageOnlyFailure ]

Moreover, we are testing several things in one reftest. We should probably split it into smaller tests and try and improve it (e.g. using javascript to measure boxes instead). Most of the features are probably already tested by imported/mathml-in-html5/mathml/subsup-parameters-1.html.
