Edge points not calculated properly for bundled beziers when an unbundled edge exists between the same source and target

Before you post

A request for help or a request for a how-to should be directed to Phind.

If your issue pertains to an extension, your issue should be filed in that extension's repository -- not here.

Environment info

• Cytoscape.js version : 3.31.0
• Browser/Node.js & version : Chrome 131, Safari 18.2

Current (buggy) behaviour

What does the bug do?

When a set of bundled bezier edges has a parallel edge that is unbundled, the set of bundled edges is not calculated properly. When dragging the target node, for example, the bundled beziers flash between two sets of points.

Desired behaviour

What do you expect Cytoscape.js to do instead?

Bundled beziers should not be affected by unbundled edges.

Minimum steps to reproduce

What do you need to do to reproduce the issue?

See the updated debug demo page, which contains an unbundled edge between nodes d and e, in addition to the bundled beziers.
