Describe the bug

I want to perform some operations when the tab or browser is closed. So I intended to do some operations in page.on_disconnect. However, when I refresh the page, the on_disconnect function is also called, which is something I don't want to happen.

Code sample

Code

import flet as ft


def main(page: ft.Page):
    page.add(ft.Text('hello world!'))
    page.update()

    page.on_close = lambda e: print('closed!')


ft.app(target=main, view=ft.WEB_BROWSER)

To reproduce

Run example code.

Expected behavior

I hope that the on_disconnect function will only be called when the page or the browser is closed.

Sorry, there is an error in the sample code. It should be page.on_disconnect.
