Self-loop not drawn

[maickrau]

In the linux version of release v2022.09, the edge of a node looping on itself is not drawn. Here is a graph to reproduce:

S    1    A
L    1    +    1    +    0M

This is how bandage displays the graph:

The graph information correctly counts the edge, but it is not drawn.
