Double clicking flet.WindowDragArea causes window to expand even when page.window_frameless = True and/or page.window_maximizable = False

[JasonSettings]

Description

Setting page.window_frameless = True and using flet.WindowDragArea instead of native title bar to move page around is somewhat awkward because Windows "expand window by double clicking title bar" behaviour is still in effect.

Code example to reproduce the issue:

import flet as ft


def main(page: ft.Page):
    page.window_bgcolor = ft.colors.TRANSPARENT
    page.bgcolor = ft.colors.TRANSPARENT
    page.window_frameless = True
    
    page.add(
        ft.WindowDragArea(
            ft.Container(
                width=300,
                height=300,
                bgcolor=ft.colors.BROWN_700,
                border_radius=ft.border_radius.all(20),
                padding=20,
                alignment=ft.alignment.center,
                content=ft.Column(
                    controls=[ft.Text('Double click here', size=28)],
                    alignment='center',
                ),
            )))
    page.update()


if __name__ == '__main__':
    ft.app(target=main)

Describe the results you received:

Double clicking anywhere inside of drag area causes window to enter this weird pseudo-maximized state - the expand animation plays, the window moves to upper left corner (or maybe center) and locks in this "maximized" state until you drag it a bit.
Also placing the window near display border invokes Windows expand/layout manager.

Describe the results you expected:

Would be cool to fix (or I guess block) this behaviour. Not sure if it is actually possible.

I think we could add maximizable property to WindowDragArea, so double-click could be enabled/disabled programmatically - how does it sound?

[JasonSettings]

Any method you deem convenient and logical will suffice (I'm not really in a position to discuss details with a dev)! In my opinion, the option to turn off/block maximization completely is needed for drag area.
