Having two forest figures and using tikzmark

Question

I have two forest figures in the same figure environment and I want to use tikzmark in both of them. The outcome is supposed to look like this:

My current code is this:

\documentclass{article}                          


\usepackage{forest}

\usetikzlibrary{tikzmark}

\forestset{
sn edges/.style={for tree={parent anchor=south, child
anchor=north,align=center,base=bottom,
where n children=0{tier=word}{}}}
}


\newcommand{\spirit}[1]{%
{\renewcommand{\arraystretch}{0}%
\begin{tabular}[t]{@{}c@{}}%
\ibox{#1}\\[-3.2mm]
\large/\\%
\end{tabular}}}

\newcommand{\sliste}[1]{%
\mbox{%
$\left\langle\mbox{\upshape\scshape #1}\right\rangle$}%
}

\def\ibox#1{\mbox{}\setbox2=\hbox{$\scriptstyle #1$}\lower.2ex\vbox{\hrule
        \hbox{\vrule\kern1.25pt 
        \vbox{\kern1.25pt\box2\kern1.25pt}\kern1.25pt\vrule}\hrule}}

\begin{document}


\begin{figure}
\hfill\resizebox{0.47\linewidth}{!}{%

                [er]]

The problem is that I do not know how to draw the arrows. I put the commands for the first figure after the first figure and the ones for the second figure after the last one, but this did not work. So the current minimal example put all drawing commands after the last figure but this does not work either:

Edit: The solution below worked fine until I updated to texlive 2014 and did all updates. Now I get:

Is there anything I can do?

Answer 1

You had scaled after remembering the coordinates, which is the wrong order:

\documentclass{article}
\usepackage{forest}

\usetikzlibrary{tikzmark}

\forestset{
sn edges/.style={for tree={parent anchor=south, child
anchor=north,align=center,base=bottom,
where n children=0{tier=word}{}}}
}


\newcommand{\spirit}[1]{%
{\renewcommand{\arraystretch}{0}%
\begin{tabular}[t]{@{}c@{}}%
\ibox{#1}\\[-3.2mm]
\large/\\%
\end{tabular}}}

\newcommand{\sliste}[1]{%
\mbox{%
$\left\langle\mbox{\upshape\scshape #1}\right\rangle$}%
}

\def\ibox#1{\mbox{}\setbox2=\hbox{$\scriptstyle #1$}\lower.2ex\vbox{\hrule
        \hbox{\vrule\kern1.25pt 
        \vbox{\kern1.25pt\box2\kern1.25pt}\kern1.25pt\vrule}\hrule}}
