I am using forest package to write some algebra with planar trees. However, when I combine automatically sized brackets with my forest picture, the bracket size and position is completely wrong: it goes all the way below the forest. How do I get the adequately sized and positioned brackets?
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{forest}
\begin{document}
$$\left ( \begin{forest}
for tree = {grow'=90,circle, fill, minimum width = 4pt, inner sep = 0pt, s sep = 13pt}
[{},phantom
[{},name = one [[]] [[][]] ]
[{},name = two [[]] [[]] ]
]
\draw[black] (one) -- (two);
\end{forest},
\begin{forest}
for tree = {grow'=90,circle, fill, minimum width = 4pt, inner sep = 0pt, s sep = 13pt}
[{},phantom
[{},name = one [[]] [[][]] ]
[{},name = two [[]] [[]] ]
[{},name = three [ [][]]]
[{},name = four [ [] [] []] [[]] ]
]
\draw[black] (one) -- (two) -- (three) -- (four);
\end{forest} \right )$$
\end{document}
