[BUG] track progressbar is not working correctly with asyncio after rich 4.1.0

[Niraj-Kamdar]

Describe the bug
track stops iterating after producing one value while running asynchronously.

To Reproduce
Following code is just to simulate bug. I am using rich progress bar to track progress of asynchronous downloading tasks.

async def sleeper(val):
    await asyncio.sleep(1)
    return val


async def scheduler():
    tasks = [sleeper(i) for i in range(10)]
    total_tasks = len(tasks)
    for task in track(
            asyncio.as_completed(tasks),
            description="Processing...",
            total=total_tasks,
    ):
        await task


def get_event_loop():
    try:
        loop = asyncio.get_event_loop()
    except RuntimeError:
        loop = asyncio.new_event_loop()
        asyncio.set_event_loop(loop)
    if sys.platform.startswith("win"):
        if isinstance(loop, asyncio.SelectorEventLoop):
            loop = asyncio.ProactorEventLoop()
            asyncio.set_event_loop(loop)
    return loop


def run_coroutine(coro):
    loop = get_event_loop()
    aws = asyncio.ensure_future(coro)
    result = loop.run_until_complete(aws)
    return result


if __name__ == "__main__":
    run_coroutine(scheduler())

Platform
What platform (Win/Linux/Mac) are you running on?
I have tried on both Linux and Windows and both are producing same bug.

What terminal software are you using?
bash terminal on linux and powershell on windows.

Which version of Rich?
rich>=4.1.0 produces this bug. Works fine in rich<=4.0.0

Thanks! It's working fine now.
