Bug: Two Datepicker Opening Issue

[perna-python]

Description

I have encountered a issue in my web application. In a specific view, I have added a datepicker component, and when I try to open it, two datepickers appear on the screen. The first datepicker closes when I press OK or Cancel and then the second one appears and works as it should

Code example to reproduce the issue:

import datetime
import flet as ft

def main(page: ft.Page):
    page.title = "Example DatePicker"
    
    def change_date(e):
        print(f"Date picker changed, value is {date_picker.value}")

    def date_picker_dismissed(e):
        print(f"Date picker dismissed, value is {date_picker.value}")

    date_picker = ft.DatePicker(
        on_change=change_date,
        on_dismiss=date_picker_dismissed,
        first_date=datetime.datetime(2023, 10, 1),
        last_date=datetime.datetime(2024, 10, 1),
    )

    page.overlay.append(date_picker)

    date_button = ft.ElevatedButton(
        "Pick date",
        icon=ft.icons.CALENDAR_MONTH,
        on_click=lambda _: date_picker.pick_date(),
    )

    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 DatePicker", on_click=lambda _: page.go("/datePicker")),
                ],
            )
        )
        if page.route == "/datePicker":
            page.views.append(
                ft.View(
                    "/datePicker",
                    [
                        ft.AppBar(title=ft.Text("Date Picker"), bgcolor=ft.colors.SURFACE_VARIANT),
                        date_button,
                    ],
                )
            )
        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)
