Remove footnote indent for Beamer

Question

I saw this excellent answer Left-Aligning footnotes in Beamer, and am curious how to modify this to remove the left indentation on the footnote. I've tried adding \parindent=0pt as well as changing \footnotesep to \z@ for zero space to no avail.

Note that How to remove indentation in footnote? does not work for Beamer.

% how to get rid of indent?
\documentclass{beamer}

\makeatletter
\renewcommand<>\beamer@framefootnotetext[1]{%
  \global\setbox\beamer@footins\vbox{%
    \hsize\framewidth
    \textwidth\hsize
    \columnwidth\hsize
    \unvbox\beamer@footins
    \reset@font\footnotesize
    \@parboxrestore
    \protected@edef\@currentlabel
         {\csname p@footnote\endcsname\@thefnmark}%
    \color@begingroup
      \uncover#2{\@makefntext{%
        \rule\z@\footnotesep\ignorespaces\parbox[t]{.9\textwidth}{#1\@finalstrut\strutbox}\vskip1sp}}%
    \color@endgroup}%
}
\makeatother

\begin{document}

\begin{frame}
Some text\footnote{This is a footnote spanning more than one line, that now after some modifications is aligned left.}
Some other text\footnote{This is another footnote spanning more than one line, that is also aligned left.}
\end{frame}

\end{document}

Instead of redefining the footnote, you could simply do something like \addtobeamertemplate{footnote}{\hskip -2em}{}.

\documentclass{beamer}
\addtobeamertemplate{footnote}{\hskip -2em}{}
\begin{document}
\begin{frame}
Some text.\footnote{This is a footnote with indent removed.}
Some other text.\footnote{This is a subsequent footnote that is also not indented and spans more than one line.}
\end{frame}
\end{document}

Insert negative \hskip to \footnotesep like this:

\hskip -1.5em    
    \color@begingroup
      \uncover#2{\@makefntext{%
        \rule\z@\footnotesep\ignorespaces\parbox[t]{.9\textwidth}{#1\@finalstrut\strutbox}\vskip1sp}}%
    \color@endgroup}%

Full code:

\documentclass{beamer}

\makeatletter
\renewcommand<>\beamer@framefootnotetext[1]{%
  \global\setbox\beamer@footins\vbox{%
    \hsize\framewidth
    \textwidth\hsize
    \columnwidth\hsize
    \unvbox\beamer@footins
    \reset@font\footnotesize
    \@parboxrestore
    \protected@edef\@currentlabel
   {\noindent\csname p@footnote\endcsname\@thefnmark}%
    \hskip -1.5em    
    \color@begingroup
      \uncover#2{\@makefntext{%
        \rule\z@\footnotesep\ignorespaces\parbox[t]{.9\textwidth}{#1\@finalstrut\strutbox}\vskip1sp}}%
    \color@endgroup}%
}
\makeatother
\begin{document}

\begin{frame}
Some text\footnote{This is a footnote spanning more than one line, that now after some modifications is aligned left.}
Some other text\footnote{This is another footnote spanning more than one line, that is also aligned left.}
