Serialization Methods `var_to_bytes_with_objects` and `bytes_to_var_with_objects` Not Preserving Instance Property Values about godot HOT 3 OPEN

PROPERTY_USAGE_DEFAULT is used by default for exported properties, in _get_property_list(), etc. But by default, script variables are not exported at all:

var a # SCRIPT_VARIABLE
@export_storage var b # STORAGE | SCRIPT_VARIABLE
@export var c: int # DEFAULT | SCRIPT_VARIABLE

We should probably clarify this in the documentation.

You should export¹ the property so that it is taken into account by the duplicate() method and serialization.

This is documented here, but we need to copy the note into descriptions of similar methods, see #80585.

@dalexeev adding the @export_storage annotation works as expected , Thank you .. however i just find the documentation confusing a little bit when it says :

Note: Not all properties are included. Only properties that are configured with the @GlobalScope.PROPERTY_USAGE_STORAGE flag set will be serialized.

Then when we take a look at where this link goes :

PropertyUsageFlags PROPERTY_USAGE_STORAGE = 2
The property is serialized and saved in the scene file (default).

The way i interpreted the (default) is that this flag is already set by default for the class' properties. isn't it the case or am i missing something .
