Connections can get frozen on removal

[nathan-haines]

When I was working locally I noticed that on occasion when I disconnected two nodes, the connection would become frozen and I could no longer interact with it. I was able to reproduce this on the demo example as well. See below:

It appears to happen when you release the connection very close to where it was connected.

@nathan-haines Thanks for reporting this issue. I need to try it out locally to reproduce this..
