Making x-saved tikz pictures less color blind

xsavebox has the ability to color saved boxes according to the ambient text. tikzpictures have the same ability. However, the combination of these does not seem to have this ability.

documentclass{article}
usepackage{tikz}
usepackage{xsavebox}
begin{xlrbox*}{SavedPar}%
boxed paragraph 
end{xlrbox*}
newcommandTestTikZ{begin{tikzpicture}
draw circle[radius=1cm];
end{tikzpicture}}
begin{xlrbox*}{SavedTikZ}%
TestTikZ
end{xlrbox*}

begin{document}
test, theSavedPar, TestTikZ, theSavedTikZ

vskip1cm
textcolor{red}{test, theSavedPar, TestTikZ, theSavedTikZ}
end{document}

As you can see, the circle on the bottom left is not colored even though the tikzpicture from the macro and the saved text box are.

The question is whether one can make the saved tikzpicture also become color sensitive.

P.S. I experimented with this thread, but could not make this work either.
