The signature for .format_map() is now incorrect:

>>> str.format_map.__text_signature__
'($self, /, mapping)'
>>> "x".format_map(mapping={})
Traceback (most recent call last):
 File "<python-input-1>", line 1, in <module>
 "x".format_map(mapping={})
 ~~~~~~~~~~~~~~^^^^^^^^^^^^
TypeError: str.format_map() takes no keyword arguments
