#331 Semibold italic as wrong old style numbers

[U_Fischer]

The italic semibold LinLibertine_RZI.otf has faulty old style number:

\documentclass{article}
\usepackage{ifluatex}
\begin{document}
\ifluatex
\font\test= "LinLibertine_RZI.otf:script=latn;language=DFLT;+onum;"
\else
\font\test= "[LinLibertine_RZI.otf]:script=latn;language=DFLT;+onum;"
\fi
\test  1234567890

\end{document}

This outputs 1234501230

The semibold version isn't normally used if one load the font with the libertine package but it one load the libertine font manually by font name than it can happen that xelatex use instead of the bold ("confuse it with the bold version") and so the problem came up in this question: https://tex.stackexchange.com/a/372529/2388.

Just for the record, this issue has been addressed in the Libertinus fonts fork.

Also there is a duplicate report of this issue at #336.
