Why is a task created with asyncio.create_task() in the below not garbage collected?

import asyncio
import gc

c = 0


async def run():
    global c
    try:
        while True:
            await asyncio.sleep(1)
            c += 1
    except Exception as e:
        print(e)


async def main():
    task = asyncio.create_task(run())
    del task
    while True:
        await asyncio.sleep(0.2)
        print(c)
        gc.collect()


asyncio.run(main())

Expected:

0
0
0
asyncio.CancelledError

Actual:

0
