I can confirm the issue with the OpenType (PostScript) version of the f.k Kikai Chokoku font[1]. From my perspective, your test code works well as a demonstration, but it feels slightly redundant for actual testing. It might be a good idea to include a dedicated font file for testing and use that in the test code, rather than selecting a suitable typeface each time.
