描述

digraph {
  rankdir=LR;
  node [ shape=record ];

  struct1 [
      label = "a|b|<port1>c";
  ];
  
  struct2 [
      label = "a|{<port2>b1|b2}|c";
  ];
  
  struct1:port1 -> struct2:port2 [ label="xyz" ];
}

is rendered as following, the edge does not comes from "c" part, but from the middle of struct1

According to https://sketchviz.com/graphviz-examples, it should be rendered as this (the right part, ignore the line style)

研究方向
Investigate how the markdown preview.nvim plugin renders Graphviz DOT diagrams. Look at the rendering pipeline, possibly in the markdown parser or the preview engine. Compare with the correct rendering from Sketchviz. The issue is that edges from record nodes point to the wrong port; likely a bug in mapping DOT port names to geometry.
