   Authors can make elements on a document to be stretched with different
   fonts, e.g.,

   To request the use of STIX fonts, you can add a <style>...</style> with:
   <mo myfonts="stix">...</mo> with the associated CSS declaration
   mo[myfonts="stix"]::-moz-math-stretchy {
     font-family: STIXNonUnicode, STIXSizeOneSym, STIXSize1, STIXGeneral;
   }

   To request the use of Asana fonts, you can add a <style>...</style> with:
   <mo myfonts="asana">...</mo> with the associated CSS declaration
   mo[myfonts="asana"]::-moz-math-stretchy {
     font-family: Asana Math;
   }

   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.
