### Godot version

Godot 4.0 RC 2

### System information

Windows 11

### Issue description

As the title states you get no autocompletion when statically typing.
Of course the code still works, but it shouldn't be neccessary to cast an object to a type it already is.

### Steps to reproduce

1. Create child class with some functionality

2. Get node in parent class and call childs function
