On_submission_change - submission is completed twice

[FlorianJacta]

Issue

The callback is called twice with the same parameters. It leads to notifying twice the user that the scenario is completed.

How to replicate

from taipy.config import Config
import taipy as tp
from taipy.gui import Gui, notify

# Normal function used by Taipy
def double(nb):
    return nb * 2

# Configuration of Data Nodes
input_cfg = Config.configure_data_node("input", default_data=21)
output_cfg = Config.configure_data_node("output")

# Configuration of tasks
first_task_cfg = Config.configure_task("double",
                                       double,
                                       input_cfg,
                                       output_cfg)

# Configuration of scenario
scenario_cfg = Config.configure_scenario(id="my_scenario",
                                         task_configs=[first_task_cfg],
                                         name="my_scenario")

def notify_from_submissions(state, submittable, details):
    submission_status = details.get('submission_status')

    if submission_status == 'COMPLETED':
        print("COMPLETED")
        print(submittable)
        print(details)
        notify(state, 'success', 'Completed!')
        # Add additional actions here, like updating the GUI or logging the completion.

    elif submission_status == 'FAILED':
        print("FAILED")
        notify(state, 'error', 'FAILED!')
        # Handle failure, like sending notifications or logging the error.

if __name__=="__main__":
    tp.Core().run()
    scenario_1 = tp.create_scenario(scenario_cfg)

    scenario_md = """
<|{scenario_1}|scenario|on_submission_change=notify_from_submissions|>
"""
    Gui(scenario_md).run()

COMPLETED
COMPLETED
my_scenario
my_scenario
{'submission_status': 'COMPLETED', 'job': my_scenario > double > JOB_double_6eaad931-d606-40ad-919c-3e315f80cee3}
{'submission_status': 'COMPLETED', 'job': my_scenario > double > JOB_double_6eaad931-d606-40ad-919c-3e315f80cee3}

Expected behavior

This callback should be called once with these parameters

Environment

Taipy 3.0.0
