aiofiles: looping over file doesn't work

[Akuli]

import asyncio
from pathlib import Path

import aiofiles

FILENAME = Path.home() / ".zshrc"

async def main() -> None:
 async with aiofiles.open(FILENAME, "r") as input_fd:
 async for line in input_fd:
 print(line)

if __name__ == '__main__':
 asyncio.run(main())

scratch.py:10: error: "Coroutine[Any, Any, Iterator[str]]" has no attribute "__anext__"
Found 1 error in 1 file (checked 1 source file)

Originally reported at Tinche/aiofiles#105

I think #5724 fixed this, can you verify?

Still happens:
