### System information

### Issue description

Autocomplete doesn't work when trying to access a scene node that isn't a direct child of the scene root script, using $NodePath (Shorthand for get_node("NodePath") as per docs).

Example:

It worked in Godot 3.5:

I should mention that it works if you start by typing the name of a direct child:

But when you have many nodes in the scene and longer names it's a pain to access the last children like that.


### Steps to reproduce
