Adding / Removing nodes to EditorSelection does not refresh Inspector (after 3.2.4 rc3)

[koodikulma-fi]

Godot version:
Godot 3.2.4 rc3 and rc4

OS/device including version:
Windows 10

Issue description:
When adding nodes to selection (or removing them) via EditorSelection, the Inspector panel no longer gets refreshed - however the SceneTree is refreshed properly. It now only gets refreshed when the user selects / removes nodes as opposed to selecting from within a tool script. (Could not find a way to manually refresh the Inspector.)

Steps to reproduce:
Follow the minimal reproduction project. Below are general steps:

1. First get the EditorSelection instance from EditorInterface instance (from an EditorPlugin instance). Eg. EditorPlugin.new().get_editor_interface().get_selection()
2. Then call .add_node(my_node) or .clear() to do the changes to the selection.
3. Observe the result: SceneTree is updated, but Inspector is not. (Does not help to emit selection_changed from EditorSelection instance.)

Might be another consequence of #32908

After looking into it, I think this is not a bug. Before ##32908, any selection change would cause a cascade of calls that would edit every selected node. Now nodes need to be edited (i.e. opened in the inspector) explicitly.

EditorNode has a method called push_item, but it's not exposed. Not sure if there is a way to push something to edit in the inspector. We should add/expose such method and properly document that users have to manually edit the nodes added to selection.

@KoBeWi I am able to push things to the editor with this inspect_object() call. Is that what you are talking about?

Thanks! I had only used inspect_object for resources and selection for nodes, didn't realize inspecting works for nodes, and this is (now) intended behaviour - not a bug. So, for anyone with similar tool helpers: from 3.2.4 5c3 onwards should call EditorInterface.inspect_object(node) after calling EditorSelection.add_node(node) or EditorSelection.clear() to "refresh inspector".
