Legal Dot syntax does not render

[XANi]

This syntax:

graph route {
    d1,d2--d3,d4;
}

renders (with no CLI warnings)

but in IDEA I get nothing and a warning on bottom:

This was working few versions ago, I can't point out exactly when it broke coz I don't use the plugin often enough

[nt-gt]

I can reproduce that the graph does not render (admittedly, I get a different error - namely the one from #32).

The following can be used as a work around:

graph route {
  d1 -- d3
  d1 -- d4
  d2 -- d3
  d2 -- d4
}

(Which is sadly considerably more annoying/verbose than the original one).
