Subgraph Rank Alignment (Edited)

1

I am trying to align subgraph cluster_A A2 with B3 but when I use

{rank=same; A2 B3 }

The box around the subgraph stops working as I expected. Does anyone know how to solve this?

digraph {
    graph [compound=true]
    node [shape=rect];
    
    subgraph cluster_A {
        A2 [shape=plaintext]
        A3 [shape=plaintext]
        A2->A3 [style=invis]
        
    }
    A1 -> A2
    
    A3->A4 [ltail=cluster_A]
  
    B1 -> B2
    B2 -> B3
    B3 -> B4
    B4 -> B5
   B5 -> B6
   {rank=same; A1 B1 }
   
   { rank=same; A4 B6 }
}

setting rank across clusters doesn’t work as desired unless you set newrank=true (newrank | Graphviz)

digraph {
    graph [compound=true   newrank=true]   // added newrank
    node [shape=rect];
    
    subgraph cluster_A {
        A2 [shape=plaintext]
        A3 [shape=plaintext]
        A2->A3 [style=invis]
    }
    A1 -> A2  // you might add lhead
    
    A3->A4 [ltail=cluster_A]
  
    B1 -> B2
    B2 -> B3
    B3 -> B4
    B4 -> B5
    B5 -> B6
   {rank=same; A1 B1 }
   {rank=same; A4 B6 }
   {rank=same A2 B3}
   {rank=same A3 B4}  // optional, keep A3 close to A2
}
