func_attrs = [
    "__code__",
    "__defaults__",
    "__doc__",
    "__closure__",
    "__globals__",
    "__dict__",
]

These are the attributes autoreload tries patching when updating a changed function. When using deduperreload (the default) it will also patch kwdefaults. imo kwdefaults should be added to func_attrs so it is patched when not using deduperreload, along with annotations and type_params which neither the old code or the new deduperreload is updating currently.
