Bug description:
Problem is, wait_for sometimes raises CancelledError instead of TimeoutError.
Had a look on recent changes and updated Lib/asyncio/timeouts.py with #113819 by @serhiy-storchaka which seemed similar.
I failed to do to reproduce with sleep only/without httpx.
As the exception raised is either TimeoutError or CancelledError, I consider this an cpython issue.
