### Godot version

4.0.beta.16

### System information

N/A

### Issue description

```gdscript
func _run() -> void:
	click_this_function_doesnt_jump_to_its_line() # this works
	self.click_this_function_doesnt_jump_to_its_line() # add self breaks click-jump























































func click_this_function_doesnt_jump_to_its_line():
	pass
```

Ctrl + Click on self.click_this_function_doesnt_jump_to_its_line(), it won't jump to its definition.
