[0.15.12] Train GUI opens on default key binding in Map View

[Gegell]

I have changed the "Open object's GUI" keybinding to the right mouse button. In the normal view the trains GUI can only be opened by the right mouse button as expected. However in the map view (zoomed out enough for the radars not to take effect) it opens only over the default keybinding (left mouse button). Furthermore in the map view, when in radar range, (zoomed in enough, for it to take effect) both keybindings work. I tested it with other keybindings and the same issue occured.
I thaught it's supposed to use the keybinding set in the options instead of the default value so I submitted it as a bug.

All map interaction is bound to the "drag map" key binding.
