The problem is that with the stix 2 math fonts, parentheses don't grow in a font with active +ssty feature when using luatex with the context based fontloader. (With xelatex everything is fine, harfbuzz seems to do it as wanted).
Addition: There is also a bug report on stix-site.
https://sourceforge.net/p/stixfonts/tracking/86/
(But I don't know if it is really a bug in the font as xelatex with harfbuzz has no problems.) I don't know what harfbuzz does but the font definitely does some ssty mapping to rather simple glyphs with no extensible parts so basically it's a font bug. If xetex catches it, find but it's still a bug. Anyway,
