Nodes overlap in complex graphs

[lmis-frontend]

Hello, We use the plugin (graphview: ^1.1.1) with the Sugiyama algorithm. In more complex graphs, the individual nodes often overlap. As can be seen in the attached image, each branch is followed by a green and a red path. However, in the marked area, the red and green paths overlap.

Do you know what could cause this problem and how to fix it?
