[issue33786] @asynccontextmanager doesn't work well with async generators

Ned Deily added the comment: I'm still not sure exactly what happened here but it looks like the backport to 3.7 (PR 7506) from the original fix in master (pre-3.8) (PR 7467) failed but the backport to 3.6 (PR 7507) succeeded. And then it was backported a second time to 3.6 (PR 7514)
