Issue: When trying to connect two Notch Bins, the connection link will not connect and instead attaches somewhere random in the network.
Repro Steps:
* Place two bins in the network
* Without ungrouping, add a connection to the edge of each group
* Create a link between the connections
Expected Result: Groups connect with link
Actual Result: Link attaches to random spot within network, one end attached to the original group, and the other not attached to any node or group
