[zzzamo]

Tested versions

Issue is present in Godot_v4.3-dev6 I tested on Godot_v4.2.2-stable and it works Ok

System information

Windows 10 - Godot_v4.3-dev6

Issue description

Whenever I try adding Resource to a Dictionary it brings me this error

editor/editor_properties.cpp:1328 - Cannot reliably represent '-9223372002008496859' in the inspector, value is too large.

Steps to reproduce

1. Add new Node
2. Add a new script to the node
3. Add 2 exports to the script and use _ready to assign resource to a value in the dictionary

   
   extends Node

@export var dictionary:Dictionary @export var resource:Resource

func _ready() -> void: dictionary[0] = resource

4. create new tres file from a Resource
5. put newly created tres file on the inspector under resource variable on node
6. run the application
7. go to remote tab on scene
8. select the node and look for the dictionary variable
9. expand it
10. you'll get the error mentioned before

Bisecting points to #88231 as the culprit:
