[issue46761] functools.update_wrapper breaks the signature of functools.partial objects

Hmm, interesting.  I wasn't involved in writing the `follow_wrapper_chains` feature, so I don't know why it's there.  I wonder if some digging through the revision history of `functools.py` and `inspect.py` would yield insight.
