Describe the bug

When placing the same control in two TabBarViews of Tabs, only the last control will be modified when changing its value (theoretically, they should have the same value)

Code sample

Code

import flet as ft


def main(page: ft.Page):
    test_input = ft.TextField()
    page.add(
        ft.Tabs(
            selected_index=1,
            length=2,
            expand=True,
            content=ft.Column(
                expand=True,
                controls=[
                    ft.TabBar(tabs=[ft.Tab(label="Tab 1"), ft.Tab(label="Tab 2")]),
                    ft.TabBarView(
                        expand=True,
                        controls=[ft.Container(content=test_input), ft.Container(content=test_input)],
                    ),
                ],
            ),
        )
    )


if __name__ == "__main__":
    ft.run(main)

To reproduce

Steps to reproduce: 1.Run the repro code. 2.Input any value in the input box of Tab 1, switch to Tab 2, and there is a value in the box of Tab 2. However, when switching back to Tab 1, there is no value in Tab 1.
