Non-commuting draw options

[AndrewMathas]

Brief outline of the bug

My understanding is that the MWE below should produce two circles with a green boundary and a yellow fill. However, swapping the order of the style commands inside the \draw command results in the fill=yellow style being ignored:

Minimal working example (MWE)

\documentclass{article}
\usepackage{tikz}
\begin{document}

  \begin{tikzpicture}
    \draw[green,fill=yellow] (0,0) circle [radius=1];
    \draw[fill=yellow,green] (2,0) circle [radius=1];
  \end{tikzpicture}

\end{document}

This is expected behavior.

Using <color> as option key is equivalent to color=<color> (see https://tikz.dev/tikz-scopes#sec-12.4.1), which

sets the color that is used for fill, drawing, and text inside the current scope. Any special settings for filling colors or drawing colors are immediately “overruled” by this option. _{see https://tikz.dev/tikz-actions#pgf./tikz/color}
