Accessing Swash Glyphs in Minion Pro Italic

Consider the following MWE:

documentclass{article}
usepackage{fontspec}
begin{document}
 fontspec: {fontspec{MinionPro-It} Qa He}
 
 text swash: {fontspec[RawFeature=+cswh]{MinionPro-It} Qa He}
end{document}

which with xelatex produces the following:

However, with lualatex the two lines are identical. I suspect the issue is that the swash glyphs in Minion Pro are accessed contextually and lualatex is interpreting the substitution rules differently. To this end I am wondering how one can access the glyphs? Opening up the font in fontforge one can see there is a swash substitution table in gsub although as it does not have a standard name it does not appear to be accessible via fontspec.

Edit

I found a copy of TexLive 2019 on this machine. Running this through it works perfectly with both lualatex and xelatex. I am therefore reasonably confident that there has been a regression in behavior between TL2019 and TL2021.
