ui update will stop when socket id goes to more than 257

[USAmy]

I met a strange issue, I write a demo to update the value in UI. but I am looking for the socket.io message, I find after the next_message_id go to 257, then the UI will not refresh or seems it is can not refresh. but the data from server still update.
any ony can give me some suggestion. Thanks very much
here is a screen:

here is code:

from nicegui import ui
import asyncio

data = {"value": 100}
message_counter = 0
main_container = None

async def update_data_periodically():
    global data, message_counter, main_container
    while True:
        await asyncio.sleep(1)
        data["value"] += 1
        print(f"Data updated: {data['value']}")

        if message_counter >= 256:
            print(f"Message count reached {message_counter}, resetting connection.")
            message_counter = 0
            #with main_container:
                # 使用 Socket.IO 的重连方法
                #await ui.run_javascript('socket.io.engine.close()', timeout=5)

@ui.page('/')
def main_page():
    global message_counter, main_container

    main_container = ui.column()

    with main_container:
        label = ui.label(f"实时数据: {data['value']}")

        def update_label():
            global message_counter
            label.text = f"实时数据: {data['value']}"
            message_counter += 1

        ui.timer(1, update_label)

    asyncio.create_task(update_data_periodically())

ui.run(port=9999, reconnect_timeout=10)

run with nicegui = 2.9.0
python = 3.8.0
ubuntu 18.04.6
armv7(Cortex-A12)

seems change nicegui version == 2.2.0, the issue missed. And now the server can be hold the long connection and keep data refreshed.

@USAmy This sounds like a very strange bug in version 2.9. Of course you can downgrade to 2.2 which doesn't use "ack" messages at all. But it would be great to understand what is going on.

I wonder why the _id jumps to 3023175937 right after acknowledging message 257. Unfortunately I can't reproduce the problem yet. But maybe you can help narrowing it down. Can you reproduce the problem with the following minimal code?

from nicegui import ui

@ui.page('/')
def main_page():
    number = ui.number(value=0)
    ui.timer(0.1, lambda: number.set_value(number.value + 1))

ui.run()
