[Bug]: Standalone Link Routing with Libavoid throws error for crowded links and brakes Paper

[KMordalski]

Current versus expected behaviour

When user creates more than a few links (around 7)* between 2 elements and then moves third element near the links the Paper freezes or breaks in non-deterministic way.

*The higher value of idealNudgingDistance parameter the lower number of links is required to reproduce the issue.

Similar issue has been reported for libavoid-js which is used by JointJs.

Expected behavior:

As a user I expect to have reliable standalone routing which not break.
JointJs should gracefully handle libavoid failure and keep diagram working.

Steps to reproduce

Naive reproduction steps:

1. Go to Standalone Link Routing with Libavoid demo page
2. Create 7 links between two elements
3. Drag slowly third element onto created links

This issue needs to be addressed in the libavoid library.
