_unhandled_input doesnt trigger when drag

Hi,

Im new in godot, i am following a godot tutorial in version 3 and I am moving it to godot 4.
The problem I am having is that when I drag an object out of the container and release the mouse button the _unhandled_input function is not launched .

I want that when the node is dragged out of the CenterContainer or the window it returns to its original position.
This is the structure of the project, when I move one of the "InventorySlotDisplay" nodes outside of the "InventoryDisplay" the event does not pop up

I tried to set the mouse_filter in pass and ignore mode in both CenterContainer and InventoryContainer nodes and nothing is solved.
The func _unhandled_input is in the InventoryDisplay node:

And the _get_drag_data, _can_drop_data and _drop_data are in the InventorySlotDisplay node.

I have imported the project of the person who made the tutorial in godot 3 and it works correctly, reviewing it everything is the same as what I have done but the result is not the same.

I have tried several things but they do not give me the expected result.
This is the tutorial that im following, the differences with respect to my project are in the second video:

I have uploaded my project here:

Controls don't accept events outside of their area. See Control._gui_input and read over the Using Input Event page to get an understanding of how events filter.

There are a couple of ways you can approach this, but essentially you need something to handle the mouse events when the cursor is outside the area of your InventoryDisplay. You could add a script with that to a CanvasLayer or to a Viewport. I don't know what exactly the best practice is. Personally, I think I would add a Node2D with no visual appearance as either a sibling or child of your InventoryDisplay and have that handle mouse release in its _input function. Node2Ds don't care about where the event happens. They'll pick it up regardless.

award You are right, I added a 2d node as a child of inventorydisplay and I control the input there, the result is the desired one. I had to make some modifications to the code regarding the stacks.

However, this solution raises doubts in my mind. Couldn't this have some conflict? For example, if there any other script in my game that uses the same action (ui_left_mouse in this case) or something similar?
