findCycles ignores self-referencing cycles for graphs with named edges

[hcomnetworkers]

The "findCycles" algorithm does currently not return any cycles caused by self referencing nodes.

Example

const graph = new graphlib.Graph({ multigraph: true });
graph.setNode('node1');
graph.setEdge('node1', 'node1', null, 'edge1');
const cycles = graphlib.alg.findCycles(graph);

The result should be [['node1']]

If the graph was initialized without named edges

const graph = new graphlib.Graph({ multigraph: true });
graph.setNode('node1');
graph.setEdge('node1', 'node1', null);
const cycles = graphlib.alg.findCycles(graph);

The result is [['node1']]

Is there any reason why the self referencing cycles cannot be found when using named edges?
