This a bug in the base library, MuPDF. I have entered a bug report there, here is the link: https://bugs.ghostscript.com/show_bug.cgi?id=708019.
The upstream bug has been closed as resolved/invalid, so perhaps this issue can be closed as invalid after having added an explantation?
The PDF contains no embedded font and has no valid / reliable information for guessing what might be a suitable visual appearance. This also is reflected by behaviors of other PDF viewers: Some are guessing more successfully than others.
In summary we see no handle to behave differently as we currently do.
