Set of multi-edges goes outside of plot boundary with matplotlib

[szhorvat]

When using the matplotlib backend, multi edges sometimes go out of the plot boundary in undirected graphs. This does not happen in directed graphs, though.

Is this expected? Since it works correctly with directed graphs, I would expect it to work with undirected too.

ig.plot(ig.Graph.Formula('1-2-1-2-1', simplify=False))
ig.plot(ig.Graph.Formula('1->2<-1<-2->1', simplify=False))

Tested with current develop branch.

Yes.
