So I verified that one. In the test, you have some <mi>x</mi> and try to append some <span> inside it. MathMLTextElement::childrenChanged is called, but the renderer for the <span> does not seem to be attached yet when RenderMathMLToken::updateStyle is called and so WebKit still thinks it has to use italic. Moreover, MathMLTextElement::didAttachRenderers is not called and so italic style is not removed either ; maybe this is because the children of the token element are wrapped inside an anonymous RenderBlock.
I've fixed that on the MathMLLayout-bis branch by delaying the determination of when mathvariant=italic applies as well as the selection of the italic glyph to use. I'm not sure that can easily be done without the refactoring of RenderMathMLToken to remove anonymous node/style, so indeed it seems sensible to skip it at this point.</pre>
