[issue22138] patch.object doesn't restore function defaults

[Sean McCully]

Sean McCully added the comment:

So the changes submitted, take into the attributes that are part of the standard Python Data Model/Descriptors and defined as editable per documentation. 
https://docs.python.org/3/reference/datamodel.html

The thought is if a user is needing to support outside of Proxy Object (currently supported) and default descriptor attributes then mock should be special cased by user/developer. 

Please advise on current solution.
