Relink issue with not visible port

Hi there,

some time ago we have discovered that on big diagrams, with multiple nodes and links, changing links source is a bit difficult to make - when the destination port (or links end) is not visible. I cannot attach here the video, so you can check this example here:

We use the same objects and templates, as mentioned here:
https://forum.nwoods.com/t/strange-scrolling-behavior/13516/26

The only modification, after layout is complete we do is :

private void DoOnLayoutComplete(object sender, DiagramEventArgs e)
		{
			Diagram.LayoutCompleted -= DoOnLayoutComplete;
			foreach (Link link in Diagram.Links)
			{
				var d = link.Data as ConfigLinkDiagramModel;
				if (d == null || d.Points == null) continue;
				link.Route.Points = d.Points.ToList();
			}
			OnBusyChanged(false);
		}

Is this a typical behavior of the diagram? Can we somehow change it?

Best regards.

That’s odd. Have you implemented any kind of virtualization?

No. No Virtualization.

Is your Diagram.LayoutCompleted event handler being called at any time during the attempt to reconnect that existing link?

In my tests I have been unable to reproduce the problem. Could you please help us with a reproducible example?
