Asterisk is high above baseline in Mono font; problematic for code listings

MWE:

\documentclass{article}

\usepackage{fontspec}
\setmainfont{Libertinus Serif}
\setsansfont[Scale=MatchLowercase]{Libertinus Sans}
\setmonofont[Scale=MatchLowercase]{Libertinus Mono}

%\setmonofont[Scale=MatchLowercase, FakeStretch = 0.8]{Libertinus Mono}
%\usepackage{libertinus-otf}% testing
\begin{document}

The asterisk * is at high position, this is ok.

\texttt{The asterisk * is at high position also in monospaced font,
  problematic for code listings. It is small, furthermore.}

Possibly relates #63, #164

I am not familiar with OpenType fonts in general, is there some stylistic alternate here which already fixes that "issue"? I opened the font in FontForge but saw nothing particular on selecting the glyph about alternates.

The monospace asterisk was the same size as the serif one, but you were scaling down the font which made it look smaller. However, I agree that monospace asterisk should be larger and lower, so I did just that.

ah, allright, thanks for the explanation, and great to hear about this larger and lower asterisk looking forward to use it soon
