When I run the application and click the "No" button in the modal, the modal closes as It should be , but when I visit the store page and then return to the index page , clicking the "No" button in the modal doesn't close the modal.

Code sample

import flet as ft


def main(page: ft.Page):
    def close_dlg(e):
        dlg_modal.open = False
        page.update()

    dlg_modal = ft.AlertDialog(
        modal=True,
        title=ft.Text("Please confirm"),
        content=ft.Text("Do you really want to delete all those files?"),
        actions=[
            ft.TextButton("Yes", on_click=close_dlg),
            ft.TextButton("No", on_click=close_dlg),
        ],
        actions_alignment=ft.MainAxisAlignment.END,
        on_dismiss=lambda e: print("Modal dialog dismissed!"),
    )

    def open_dlg_modal(e):
        page.dialog = dlg_modal
        dlg_modal.open = True
        page.update()

    def route_change(route):
        page.views.clear()
        page.views.append(
            ft.View(
                "/",
                [
                    ft.AppBar(
                        title=ft.Text("Flet app"), bgcolor=ft.colors.SURFACE_VARIANT
                    ),
                    ft.ElevatedButton(
                        "Visit Store", on_click=lambda _: page.go("/store")
                    ),
                    ft.ElevatedButton("Open dialog", on_click=open_dlg_modal),
                ],
            )
        )
        if page.route == "/store":
            page.views.append(
                ft.View(
                    "/store",
                    [
                        ft.AppBar(
                            title=ft.Text("Store"), bgcolor=ft.colors.SURFACE_VARIANT
                        ),
                        ft.ElevatedButton("Go Home", on_click=lambda _: page.go("/")),
                    ],
                )
            )
        page.update()

    def view_pop(view):
        page.views.pop()
        top_view = page.views[-1]
        page.go(top_view.route)

    page.on_route_change = route_change
    page.on_view_pop = view_pop
    page.go(page.route)


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

Updating flet version from 0.10.3 to 0.12.0 solves the problem but , there's new bug that If you change the view several times , the application blacks out.

OS : Windows 10 Pro
flet : 0.12.0
python : 3.9.10
