Issue description

Hi,

when doing

JavaScript.get_interface("document").addEventListener("visibilitychange", callback)

with

var callback = JavaScript.create_callback(self, "_on_focus_in")

The callback is never called.

Steps to reproduce

Create a new project with a simple Node, an attached script with:

extends Node

var callback = JavaScript.create_callback(self, "_on_focus_in")
func _on_focus_in():
   print("FOCUSSSSSS IN")

func _ready():
	if OS.get_name() == "HTML5":
		JavaScript.get_interface("document").addEventListener("visibilitychange", callback)

Execute in HTML5 target. Open a browser and run the code: The callback is never executed, the message "FOCUSSSS IN" is never printed.

Minimal reproduction project

No response

You need to accept the event parameter in your callback function.
