Graph with shape=record is not rendered

[michael-l-AT]

Hello!

Thank you for this great software!

Today I encountered the following situation for the first time, that the following graph is not displayed properly.
Unfortunately, I can only guess that it is due to " {rank=same node1 node2} " or " shape=record ", because the graph is displayed as soon as either of those is removed.

Perhaps you know what the problem is and want/can quickly identify the issue.

Many thanks again and
Best regards
Michael

Problematic Graph:

digraph main {

layout="dot"
splines="spline";

subgraph cluster_1{

    
    node1 [label="{test}",shape=record]
    node2 [shape=none]

    node1->node2 [dir=back]
    
    {rank=same node1 node2}


}

}

shape=record is now repected in auto completion. However, this does not seem to work yet. It' ssome combination of the sub-graph, rank and shape:

digraph main {
	node1 [label="{test}", shape=record]
	node1->node2 [dir=back]
	{rank=same node1 node2}
}

This probably trips viz.js internally. Maybe updating it to a newer version of graphviz fixes this.
