After bug 124836 and bug 139582, we have platform-independent tests for token elements, multiscripts, mfenced and foreign content: fred@debian:~/webkit/WebKit$ ls LayoutTests/accessibility/math* LayoutTests/accessibility/math-fenced.html LayoutTests/accessibility/math-foreign-content.html LayoutTests/accessibility/math-mo-fences-and-separators.html LayoutTests/accessibility/math-multiscript-attributes-expected.txt LayoutTests/accessibility/math-multiscript-attributes.html LayoutTests/accessibility/math-text.html I'm not sure how many MathML elements we support in ATK but we could definitely add more tests, probably importing those from mac: fred@debian:~/webkit/WebKit$ ls LayoutTests/accessibility/mac/math* LayoutTests/accessibility/mac/math-alttext-expected.txt LayoutTests/accessibility/mac/math-alttext.html LayoutTests/accessibility/mac/mathml-elements-expected.txt LayoutTests/accessibility/mac/mathml-elements.html LayoutTests/accessibility/mac/mathml-line-fraction-expected.txt LayoutTests/accessibility/mac/mathml-line-fraction.html LayoutTests/accessibility/mac/mathml-multiscript-expected.txt LayoutTests/accessibility/mac/mathml-multiscript.html LayoutTests/accessibility/mac/mathml-root-expected.txt LayoutTests/accessibility/mac/mathml-root.html
