\setmathfontface does not respects Style key in lulatex

[borisveytsman]

Description

\setmathfontface does not recognize Style= key in font options if luatex engine is used

Add info or delete as appropriate:

• Relevant for LuaTeX
• Issue tracker has been searched for similar issues

Minimal example demonstrating the issue

\documentclass{article}
\usepackage{unicode-math}
\setmathfontface\symbsw{Arsenal-Regular.otf}[Style=Swash]
\begin{document}
$\symbsw{ABCD}$
\end{document}

Further details

This example defines a swash alphabet in XeLaTeX, but LuaLaTeX drops the swashes. Rawfeatures=swsh has the same effect

\setmathfontface does not seem to set mode=base which is required in LuaTeX for fonts used in Math mode.

The corresponding fontspec/unicode-math font option would be Renderer=Basic.
