Scrolling in a tab isn't smooth in Windows

[YouCantCMe]

Using the latest pre release of Flet in Windows 10, scrolling with your middle mouse isn't smooth in a tab. Video below:

Example code:

def main(page: ft.Page):
    page.window_resizable = False
    page.window_width = 400
    page.window_height = 300
    text = ft.Text("Hello, world!")
    container = ft.Container(
        ft.Text("Container"),
        alignment=ft.alignment.top_left,
        col=ft.colors.BLACK,
        height=400,
        key="C",
    )
    text2 = ft.Text("Hello, world!")

    col_content = ft.Column(controls=[text,container,text2], scroll=True)

    tabs = ft.Tabs(
        expand=1,
        tabs=[
            ft.Tab(
                text="Example",
                content=ft.Container(
                    content=col_content,
                ),
            ),
        ],
    )

    page.add(tabs)

ft.app(target=main)

To achieve smooth scrolling, the documentation suggests using ft.ListView https://flet.dev/docs/controls/listview/

It was tested on Windows and Linux and it works fine. There is not enough data inside to scroll. Try it like this:

import flet as ft

def main(page: ft.Page):
    page.window_resizable = False
    page.window_width = 400
    page.window_height = 300
    text = ft.Text("Hello, world!")
    container = ft.Container(
        ft.Text("Container"),
        alignment=ft.alignment.top_left,
        bgcolor=ft.colors.BLACK38,
        height=400,
        key="C",
    )
    text2 = ft.Text("Hello, world!")

    col_content = ft.Column(
        controls=[
            text,
            text,
            text,
            text,
            text,
            text,
            text,
            text,
            text,
            text,
            text,
            text,
            text,
            text,
            container,
            text2],
        scroll=ft.ScrollMode.ALWAYS
    )

    tabs = ft.Tabs(
        expand=1,
        tabs=[
            ft.Tab(
                text="Example",
                content=ft.Container(
                    content=col_content,
                ),
            ),
        ],
    )

    page.add(tabs)

ft.app(target=main)

It still doesn't scroll smoothly using the middle mouse wheel with the provided example.

Hey, was anyone able to solve it? For me the scrolling is not smooth using the touch pad on my laptop (mouse), the normal mouse wheel works fine.
