Second load of xcolor uses options

[dginev]

This is an extraction from arXiv:1912.05909. In that article, an independent .sty package loads xcolor without options. Later in the preamble, an explicit second load of xcolor - this time with dvipsnames takes place. Interestingly, that load appears to execute and the options activate, so that the NavyBlue color name is recognized.

In latexml, I beleieve once xcolor has been loaded once, the second load is ignored. A bit of a puzzle how best to upgrade the options processing to get parity.

\documentclass{article}
% initially due to some foo.sty dependency
\usepackage{xcolor}
% it appears to activate despite being the second load:
\usepackage[dvipsnames]{xcolor}
\begin{document}
\textcolor{NavyBlue}{test}
\end{document}

I stumbled on this again, in the following variation:

\documentclass{article}
\usepackage{pgf}
\usepackage[table]{xcolor}

\begin{document}
\begin{tabular}{c}
  \cellcolor{gray!50}Hello 
\end{tabular}
\end{document}

Where the expected behavior is that after the load of pgf also loads xcolor, the second load will pass the [table] option and have colortbl.sty loaded in turn, defining \cellcolor.
