Issue description

I have an scene object with Area2D and collision shape. It's input_event signal runs twice if this object is a child of CanvasLayer. If I put it directly under root node it runs once. If I make an Area2D node directly in scene signal runs once too. In Godot 3.5 in the same project in all cases it runs once.

extends Node2D
@export var id := 0

func _on_Area2D_input_event(viewport, event, shape_idx):
	if event is InputEventMouse and event.is_pressed() :
		prints("Hit!", id)

Steps to reproduce

Open the sample project, run it and click on icons. Check the output.

Correction, if Area2D is a child of CanvasLayer event hits twice too.
I forgot to make it child

I had the same problem. Any updates here? Is there a workaround?
