森林：文件夹上的垂直空间增长

Question

我想“动态”计算节点必须具有的垂直空间以避免重叠，并且最好将它们对齐，目前我有一个名为的样式，arrowed folder它几乎是 grow 样式的副本folder。但是，文件夹和我的都存在当文本“较大”时节点重叠的问题

\documentclass{article}
\usepackage[edges]{forest}
\usepackage{xcolor}

% Forest arrowed folder edges

\forestset{
    declare dimen register=arrowed folder indent,
    arrowed folder indent=0.45em,
    arrowed folder/.style={
        parent anchor=-children last,
        anchor=parent first,
        calign=child,
        calign primary child=1,
        for children={
            child anchor=parent,
            anchor=parent first,
            edge={rotate/.option=!parent.grow},
            edge path'/.expanded={
                [
                    color=linecol,

                    >={Stealth[length=6pt]},
                    line width=0.5pt,
                    ->
                ]
                ([xshift=\forestregister{arrowed folder indent}]!u.parent anchor) |- (.child anchor)
            },
        },
        after packing node={
            if n children=0{}{
                tempdiml=l_sep()-1*l("!1"),
                tempdims={-abs(max_s("","")-min_s("",""))-s_sep()},
                for children={
                    l+=tempdiml,
                    s+=tempdims()*(reversed()-0.5)*2,
                },

为了修改垂直空间，我正在调整s值，但这不是一个很好的解决方案

after packing node={
    if n children=0{}{
        tempdiml=l_sep()-1*l("!1"),
        tempdims={-abs(max_s("","")-min_s("",""))-s_sep()},
        for children={
            l+=tempdiml,
            s+=tempdims()*(reversed()-0.5)*5,
        },
    },
},

我知道改变顺序有帮助，但我该怎么办，例如，如果一个节点上只有一个大孩子？
