Input filter does not allow to delete the entered character

[Legolaz7]

I copied the code here https://flet.dev/docs/controls/textfield/#input_filter
I set the input filter so that only "numbers" and "dot" values ​​are accepted
I enter numbers, and it does not allow me to delete the first value.
The code itself:

import flet as ft

def main(page: ft.Page):
    page.window.width = 400

    def textbox_changed(e):
        t.value = e.control.value
        page.update()

    t = ft.Text()
    tb = ft.TextField(
        label="Textbox with 'change' event:",
        on_change=textbox_changed,
        input_filter=ft.InputFilter(regex_string=r"[0-9.]")
    )

    page.add(tb, t)

ft.app(main)

If you remove input _filter, everything works.
