Currently variable height roots are only supported with STIX Beta fonts http://www.mozilla.org/projects/mathml/fonts/#1.9
Just curious if there is a reason Mozilla 1.9 can't use the MIT fonts if they're available and the STIX fonts aren't? Seems like since Mozilla 1.8 could do variable height roots with the MIT fonts it that code could have been used as a fallback.
(In reply to comment #2) For some of the fonts in the MIT bundle there are good reasons not to install the fonts. https://bugzilla.mozilla.org/show_bug.cgi?id=161137#c39 https://bugzilla.mozilla.org/show_bug.cgi?id=400938#c0 A subset of the fonts could be safely installed and detected and special-cased as in Mozilla-1.8. However, their handling has not been ported to the new gfx implementation, and effort would probably be better spent adding support for fonts that are likely to already be installed on the system such as Cambria Math (bug 372351) or OpenSymbol (from OpenOffice). Downloadable fonts (bug 70132) could provide a way to ensure that some suitable font will be available.

I've just had this one bite me; it can be quite insidious. Consider <m:msqrt><m:mfrac><m:mi>π</m:mi><m:mn>2</m:mn></m:mfrac></m:msqrt> which displays like the attached image --- EASILY misread to be quite a different quantity. Now, I understand that the STIX fonts may be the only font with stretchable surds, but is there any way to warn the user that what they're reading is VERY wrong? Frankly, it would be better to have the surd vertically centered and disconnected from the overbar (ie a "broken display") than it is to have the elegant but WRONG display... Landing craft have crashed for reasons like this!
The fix for bug 414277 should mean that, even without STIX fonts, Firefox 4 should not display this in a manner that looks wrong.
Depends on: scale-stretchy
Ah, thanks, Karl; looks like a good fix. And it gives me a target, or answer "until firefox 4, be sure to install STIX"
