I was just hit by the very same issue and added the following test into
`_get_action_name` to work around it:
elif isinstance(argument, _SubParsersAction):
return '{%s}' % ','.join(map(str, argument.choices))
I checked #9253 as referenced by paul j3 and like the `argument.name()`
approach as well as it's less specific.
Any chance this can be addressed one way or another?
