Describe the bug

Hi, when I use this code to close the program, the program blocks for some time before actually exiting.

Code sample

Code

def main(page: ft.Page):
    page.title = "Test App"

    def yes_click(e):
        print("Closing window....")
        page.window.destroy()
        print("Window closed.")

    button = ft.ElevatedButton(text="Close", on_click=yes_click)
    page.add(button)


ft.app(target=main)

To reproduce

After the program runs, click the close button and the program will block for a certain period of time before exiting.
