将一个节点移至森林中的另一个节点

Question

我有以下树，它是非投影的，这就是问题开始的地方 =;-)。为了能够完全绘制它，我不得不使用大量幻像节点和no edge声明，但至少除了一件事之外，它还是有效的。我不知道如何将第二个 Subj 节点移到 上ob。这有可能吗？

附言：我不知道为什么comes这么高，Linux Libertine 不会发生这种情况......

如果您想将第二个主题放在“ob”上，那么最好重新构建树。我将主题放在第一部分的顶部，并使用隐藏节点和明确绘制的边将它们链接到后面的部分。希望结构仍然相同 :) 虽然德语版本的词序似乎不对...

我还在英文单词中添加了支柱，使它们都具有相同的高度，而与它们的上升和下降无关（不在图中）。

\begin{forest}
dg edges
[V, l sep+=6pt
    [Adv, dg adjunct [deshalb;therefore] ]
    [kl{\"a}rt;resolves]
    [Subj, name=s1
        [dass;that]]
    [Subj, name=s2
        [ob;whether]]
    [hidden, phantom
        [hidden, phantom
            [N, name=n1
                [Peter;Peter]]]
        [hidden, phantom
            [N, name=n2[Klaus;Klaus]]]
        [V, name=v1
            [kommt;\strut comes]]]
    [hidden, phantom
        [V, name=v2
            [spielt;plays]]]
]
\draw (s1.south)--(v1.north);
\draw (s2.south)--(v2.north);
\draw (v1.south)--(n1.north);
\draw (v2.south)--(n2.north);
