[lltx] hyphenation disabled with polyglossia and variant=usmax

[Stephan Hennig]

Hi,

in this document

\documentclass{article}
\usepackage{polyglossia}
\setmainlanguage[variant=usmax]{english}
\begin{document}
\parbox{0pt}{\mbox{} example}
\end{document}

the word 'example' is happily hyphenated using either

  xelatex + variant=us
  xelatex + variant=usmax
  lualatex + variant=us

But not with

  lualatex + variant=usmax

Is that to be expected or a bug?

Best regards,
Stephan Hennig
