Summary0001323: ordering = out does not work when adding unconstraint edges
Description



I have a graph G where the ordering of the edges must be guranteed



Within this graph i wanted to add additional edges that should
visualize connections between nodes that should not have any
influence on the edge ordering of G.
This additional edges have the edge attributes
[weight=0,style=dotted,constraint=false]
to distinguish between the edges where the ordering should be preserved.



However, it seems that the result created by dot does not realiably
create the expected graphs. There are cases where the ordering of
edges is not preserved.



In my dot example one can see that the additional edge
1->8
destroys the ordering.
When removing the comment for the edge
1->12
the output is generated as i had expected.
Steps To Reproduce

digraph G
{
ordering = out;

0->1;
0->5;
0->9;

1->2;

5->6;
5->7;
5->8;

9->10;
9->11;
9->12;

1->8 [weight=0,style=dotted,constraint=false];
/*1->12 [weight=0,style=dotted,constraint=false];*/
}
