'fg' setting places before 'preto' setting will cause the color of 'preto' text is not set to 'fg' correctly.

The sample codes:

\begin{tblr}{hlines,vlines,
 cell{1}{1}={preto=A,appto=Z}
}
 o \\
\end{tblr}

\begin{tblr}{hlines,vlines,
 cell{1}{1}={preto=A,appto=Z,black,fg=white}
}
 o \\
\end{tblr}

\begin{tblr}{hlines,vlines,
 cell{1}{1}={fg=white,preto=A,appto=Z,black}
}
 o \\
\end{tblr}

The output:

[lvjr]

At this time fg=white is the same as preto=\color{white}, which causes problems. Need to fix it.
