Okay, I see what you're talking about in the video demo. Here's a quick 
screenshot for those who want to follow along:

Simply put, those wires ARE being displayed correctly. The *ends* *are* 
dangling. Nothing is connected to them. There is no possible way I could 
write a test that detects that a label is on the wire and somehow 
decides which end to associate it with, hiding the target.

The point of hiding the targets is to show that *that* connection point 
is correctly in use. These are not in use, so why hide the target? The 
equivalent here is the target on the label itself, which has always 
hidden when connected.

If you're going to use labels to make connections, and want the targets 
to disappear, then you'll have to place the label target on the wire 
target. This is the same as for pins, if you stick a pin in the middle 
of a wire and connect it with a junction, the *end* of the wire is still 
not connected.

I think this is correct behavior.
