Comment 2 for bug 1830227

The same happens placing the net label on a wire, but in this case the correct and wrong color are both black, so there is no visual effect.
Clicking on the wire the info bar at the bottom shows the issue.

To reproduce:
-draw a wire
-place a net label over the wire
-exit tool and click on the wire
-<NO NET> is shown in "connection name" at the bottom of the screen.
-move the label with "m" and place it exactly where it was
-click on the wire and the correct net name will be shown.
