Line intersection in version 3.0

[cb12tre]

Hi MindFreeze,
I'm not sure if this is a problem or if it just requires rewriting the code differently after updating to version 3.0.1 from version 2.4.0; in the new version the graph displays many overlapping lines.

Checklist:

• I updated to the latest version available
• I cleared the cache of my browser

Release with the issue:
3.0.0 and 3.0.1

Last working release (if known):
2.4.0

Browser and Operating System:
Vivaldi 6.7.3329.26 and Firefox 125.0.3 on Windows 11

Description of problem:
In version 2.4.0, everything is represented correctly and linearly:

In version 3.0.0 it appears like this, the data is correct but there are many intersections on the lines:

I tried to modify the lines "sort_by" and "sort_group_by_parent" but I couldn't solve the problem.

This is the code used:
