Several MathML tests are currently skipped on iOS and Mac because
1) Appropriate math fonts are not pre-installed on the systems (or even just on bots)
2) These fonts are not whitelisted.
I'm opening this for the record and also to upload and publish an old patch, but it's really something that is up to Apple to address it or not.
I landed https://trac.webkit.org/changeset/229411 to add a reference to this bug in TestExpectations files.
I also landed https://trac.webkit.org/changeset/229405 to remove the failures for tests requiring Mathematical Alphanumeric Symbols since such a font is now available on iOS 11.
I also opened bug 183446 to remove the need of Latin Modern Math for some tests. I think this could be done for the two other ones too.
We will still need pre-installed OpenType MATH fonts for the following pixel tests for vertical/horizontal/large operators:
