### Issue description

The following code from [dialogic](https://github.com/coppolaemilio/dialogic) no longer works in 4.2-dev, but does in 4.1 and before:
```gdscript
class VariableFolder:
        var data = {}
        var path = ""
        var outside
        func _init(_data, _path, _outside):
                data = _data
                path = _path
                outside = _outside
        
        func _get(property):
                property = str(property)
                if property in data:
                        if typeof(data[property]) == TYPE_DICTIONARY:
                                return VariableFolder.new(data[property], path+"."+property, outside)  ### <====== ERROR ###
                        else:
                                return DialogicUtil.logical_convert(data[property])
        
        func _set(property, value):
                property = str(property)
                if not value is VariableFolder:
                        outside._set_value_in_dictionary(path+"."+property, outside.dialogic.current_state_info['variables'], value)
                        return true
                elif VariableFolder:
                        return true
```
On compilation this will give the error
```
SCRIPT ERROR: Compile Error: Identifier not found: VariableFolder
          at: GDScript::reload (res://addons/dialogic/Modules/Variable/subsystem_variables.gd:182)
```
(line 182 is the `VariableFolder.new` line)

i bisected it to the following commit, from #79880:
