### Godot version

4.0.dev(dc3175e4cdb4e54e1c6200b6c4d07646eea95284)

### System information

Any

### Issue description

EditorPlugins that depend on the resources that Node has will not be visible when SubInspector is focused.

This is caused by two problems:

The first is caused by implicit editor deletion in Node3D. This is fixed by #70907.

The other is due to a change in inspector update timing, which is regression by #68498. Revert PR #70909 will fix this issue, but if not, we will need to update SubInspectorEditor in the correct way.

### Steps to reproduce

Select Path3D or CollisionPolygon3D and open a SubInspector such as Script.
