When two modules are glued, you can't stick to the right of the second one

[vincentcourtois]

Scenario

1. Create a first module
2. Create a second module
3. Place the second module just on the right of the first module
4. Create a third module

Anomaly

The third module can be dragged inside the second module

Wanted behaviour

We'd want the third module to be placed either on the right of the second one, or the left of the first one, but not above or below any of them

The bug was NOT linked to glued modules, but rather on finishing a drag'n'drop of module on a port.
