Alas, the original mozilla document is no longer online and it's not possible to recreate the problem reported: I've downloaded a version of it around the time of this bug report from the wayback machine, but importing it into TeXmacs was TOTALLY BROKEN because it's html5 (where the <math> tags have no xlmns attribute)

I've recently fixed this breakage (with commits starting at rev 14093), and perhaps some of the math formating import bugs originally reported. I think now TeXmacs decently imports the Mozilla torture test.

Recent versions of the "mathml torture test" can be found at
https://fred-wang.github.io/MathFonts/mozilla_mathml_test/

Leaving open for the moment because I may have introduced some bugs...

Please see the attached tm document for a version of Mozilla's MathML Torture test:

https://developer.mozilla.org/en-US/docs/Mozilla/MathML_Project/MathML_Torture_Test

The converted HTML file shows a few problems:

test #8 and #9: <choose> is not converted (the problem seems to be the <shrink-inline> tag in that macro)

test #14: mathi is converted to ⅈ

test #16: there's a large spacing after the integral sign

test #17: the double integral appears as the text "iint"

test #19 and #22: text underbrace and overbrace result in superscripts and subscripts after the brace, not text over or under the brace

test #28: Three primes are converted separately, but would like much better as a ‴ character.
