Ter duas figuras da floresta e usar o tikzmark

Question

Tenho duas forestfiguras no mesmo figureambiente e quero usar tikzmarkem ambas. O resultado deve ser assim:

Meu código atual é este:

\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}}

O problema é que não sei desenhar as setas. Coloquei os comandos da primeira figura depois da primeira figura e os da segunda figura depois da última, mas não funcionou. Portanto, o exemplo mínimo atual coloca todos os comandos de desenho após a última figura, mas isso também não funciona:

Editar:A solução abaixo funcionou bem até atualizar para o texlive 2014 e fazer todas as atualizações. Agora eu entendo:

Há algo que eu possa fazer?

Answer 1

Você escalou depois de lembrar as coordenadas, que está na ordem errada:

\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}}
