Bug 85735 (mathvariant) - Add support for @mathvariant attribute
 Frédéric Wang (:fredw) 2012-05-06 08:04:03 PDT I think this element is only partially implemented in Webkit (in Firefox too). MathJax relies on this attribute to implement various LaTeX commands. For example the values "script", "double-struck" or "fraktur" are respectively needed for \mathcal, \mathbb and \mathfrak. Frédéric Wang (:fredw) 2016-07-11 11:53:12 PDT I think this can be closed. There are some edge cases we do not support yet (e.g. we only apply mathvariant transform on token elements with a single char which corresponds to the cases used in practice) but other follow-bugs can be opened if necessary.
