Edge hover is not properly removed in dense network

[Tooa]

Hi,

take a look at this example and dive with the cursor through the middle of the network. You will notice that the "hover" is not cleaned after the cursor leaves the edge.

The issue is maybe related to this pull-request. However, the problem also occurs with the latest develop branch! I think this is the related code for hovering and here is the hovering issued.

EDIT:

I think I got the problem. See my inline comments.

hoverObject(object) {
    [...]
    // removing all edge hover highlights
    for (let edgeId in this.hoverObj.edges) {
        [...]
        // If onMouseMove in the InteractionHandler passes not undefined to the hoverObject 
       // method, but rather another edge, the hover of the old edge is not removed. 
       // This is quite likely to happen for dense networks
        else if (object === undefined) {
          this.blurObject(this.hoverObj.edges[edgeId]);
          delete this.hoverObj.edges[edgeId];
          hoverChanged = true;
        }
      }
    } 

Best Uli
