This is currently an issue with opentype math fonts: luatex doesn't know
what the values of \Umathfractiondelsize should be.
For a workaround: explicitly setting
\Umathfractiondelsize\textstyle = 12.12pt
\Umathfractiondelsize\displaystyle = 28.68pt
will set up values that closely mimic "cmsy10 at 12pt"
Ulrik Vieth (who is in CC) proposes to use DelimitedSubFormulaMinHeight
in non-display modes, but the DelimitedSubFormulaMinHeight in Cambria
Math is 3000/2048 * <atsize> == 17.58pt, which also doesn't seem right.
Since Hans converts everything to OpenType MathConstants format,
perhaps I should just add two more named entries to be parsed
in the MathConstants table?
Best wishes,
Taco
