supertabular and simple footnote customization

Question

I have a problem defining customization for footnotes marks (arabic, roman etc) inside a mpsupertabular.

In the Minimal working example I would expect the footnote mark to appear in \roman (i, ii, ...) but instead it appears in \alph (a, b, ...). I tried the same with \arabic (1,2,...) but I still get \alph.

\documentclass[twocolumn,a4paper]{article}

% Compile with xelatex

\usepackage{supertabular}
\usepackage[a4paper, margin=1in]{geometry}
\usepackage{polyglossia}
\setmainlanguage{english}

% https://en.wikibooks.org/wiki/LaTeX/Footnotes_and_Margin_Notes#Customization
% \renewcommand{\thefootnote}{\arabic{footnote}}
\renewcommand{\thefootnote}{\roman{footnote}}

\begin{document}

%\renewcommand*{\arraystretch}{3}
%\setlength\tabcolsep{1pt}

\begin{mpsupertabular}{ c c }

lalalala & lololololo \\
lalalala & lololololo \\
lalalala & lololololo \\
lalalala & lololololo \\
lalalala & lololololo \\
lalalala & lololololo \footnote{Awesome footnote}  \\
lalalala & lololololo \\
lalalala & lololololo \\
lalalala & lololololo \\
lalalala & lololololo \\
lalalala & lololololo \\
lalalala & lololololo \\
lalalala & lololololo \\
lalalala & lololololo \\

\end{mpsupertabular}

\end{document}

PS I am not interested in switching the supertabular to something else.

Answer 1

It is caused because mpsupertabular is placed on a minipage. See this answer for a more elaborate explanation.

Old result

Using the suggestion from Leo Lui: \renewcommand{\thempfootnote}{\arabic{mpfootnote}}, we get:
