Authors can make elements on a document to be stretched with different
fonts, e.g.,
To request the use of TeX fonts, you can add a <style>...</style> with:
<mo myfonts="tex">...</mo> with the associated CSS declaration
mo[myfonts="tex"]::-moz-math-stretchy {
font-family: CMSY10, CMEX10;
}
To request the use of Mathematica fonts, you can add a <style>...</style> with:
<mo myfonts="mathematica">...</mo> with the associated CSS declaration
mo[myfonts="mathematica"]::-moz-math-stretchy {
font-family: Math1, Math2, Math4;
}
Of course, if you just want all of the stretchy characters in your
document to be stretched with your preferred list, you can just do:
::-moz-math-stretchy {
font-family: [your-particular-list]
}
Note that like other fonts in the document, users can override this by
clicking the pref to override document fonts.

if there is an annotation-xml[encoding="MathML-Presentation"]
render that annotation, and ignore the first child of the

else
render the first child of <semantics> and ignore all annotations
But this cannot be expressed with CSS. As a stop-gap, just render
