Remove duplicate displayed node update call
Created by: Nehluxhes
Each time a new node is selected in the scene tree dock, both _node_selected()
and _selection_changed()
are called.
They are then both calling editor->push_item()
, resulting in potentially lots of duplicate calls downstream (eg a Gridmap node is loaded twice)
This fixes this.
Ideally I think that _node_selected() and _selection_changed() should be merged, they are redundant.
