elk.stress edge labels are not positioned as expected in unconnected graphs

[YorikHansen]

Describe the bug
When using the elk.stress algorithm to layout an unconnected graph, edge labels are not always correctly positioned on their corresponding edges. This issue appears to occur specifically when multiple nodes form a cycle (or would form a cycle if the edges were treated as undirected or bidirectional).

Example (edgeLabels.inline: true makes this even clearer)

Expected behavior
The edge labels should be at their / on their corresponding edge.

A "rollback" to v0.8 would not work, as there seem to be other issues regarding label placement: example
