List View overflows in a grey/white color when child goes invisible

[pyscripter99]

Description I have a custom component in a list view, and when that component has visibility false it causes the list view to expand the bottom to the edge of the screen in a grey/white color.

Code example to reproduce the issue:

import flet as ft
import time, random
from pocketbase import PocketBase

DEBUG = True
DB_URL = "https://example.com" if not DEBUG else "http://127.0.0.1:8090"

client = PocketBase(DB_URL)

Do you still have these issues in Flet 0.7.1?
