# savenote with tcolorbox, numbering problem

I use tikz-boxes and tcolorbox and I want to have the footnotes outside of the boxes at the bottom of the page with the same numbering with the others. To sum up, I want the tikz or tcolorbox footnotes NOT to be different with the others.

So I tried Martin Scharrer's solution to this question, that uses savenotes environment. I wrap savenotes environment around tikzpicture and tcolorbox. The tikz-box is OK, but not the tcolorbox. The footnote's text is at the bottom of the page (OK with this), but it has other numbering.

The code is below:

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{shapes,snakes}

\usepackage[most]{tcolorbox}

\usepackage{footnote}

\usepackage{environ}

\renewcommand{\thefootnote}{[\Roman{footnote}]}

\tikzstyle{mybox} = [draw=black, fill=white, very thick,
rectangle, rounded corners, inner sep=10pt, inner ysep=20pt]
\NewEnviron{tikzbox}{
\begin{tikzpicture}
\node [mybox] (box){
\begin{minipage}{0.50\textwidth}
\BODY
\end{minipage}
};
\end{tikzpicture}

}

\NewEnviron{Tbox}{
\begin{savenotes}
\begin{tcolorbox}[enhanced,
breakable]
\BODY
\end{tcolorbox}
\end{savenotes}

}

\begin{document}

Some main text Some main text Some main text Some main text Some main text Some main text\footnote{The first footnote.}

Other main text Other main text Other main text Other main text\footnote{The second footnote.}

\begin{tikzbox}
Some tikzboxed text Some tikzboxed text Some tikzboxed text\footnote{This is OK.}
\end{tikzbox}

\begin{Tbox}
Some tcolorboxed text Some tcolorboxed text Some tcolorboxed text Some tcolorboxed text Some tcolorboxed text Some tcolorboxed text\footnote{This is not OK. I want this footnote outside of the box, at the bottom of the page and with number [IV].}
\end{Tbox}

\end{document}


and this is how it looks like:
