Probable bug with scalene when profiling async code

[dheerajck]

Python 3.11.6
Scalene version 1.5.38 (2024.03.24)

Profiled values arent in the correct place

To reproduce run this
scalene --cpu-percent-threshold 0 async_await.py --cli
and press Control + C after 3 seconds from when program prints "Task 1 done"

#  async_await.py
import asyncio


async def task():
    print('Task 1')
    await asyncio.sleep(5)
    a = 1
    a = a * 100
    print('Task 1 done')


async def gather():
    print('Gather 1')
    asyncio.create_task(task())
    print('Gather 1 done')


async def main():
    await asyncio.gather(gather())
    while True:
        await asyncio.sleep(1)

    print('Main done')


if __name__ == '__main__':
    try:
        asyncio.run(main())
    except KeyboardInterrupt:
        pass

I would expect some numbers at [1] and [2]
is this the intended behaviour when profiling async code with async tasks or is it a bug
