tab completion for `choices` not work when specifying `type`

[function2-llx]

🐛 Bug report

When specifying both choices and type in parser.add_argument, the tab completion for choices will not work.

To reproduce

Create a simple script named example.py with execute permission:

#! /bin/env python

from jsonargparse import ArgumentParser
parser = ArgumentParser()
parser.add_argument('x', type=str, choices=['a', 'b', 'c'])

args = parser.parse_args()

Open a shell, calling eval "`register-python-argcomplete example.py`", and type: ./example.py <TAB>.

Expected behavior

Showing the following content as if using the vanilla argparse package:

c       b   a  --                                                                                                                
--help  -h     -- show this help message and exit

Actual behavior

In zsh, nothing shows; in bash, the following content shows:

-h                                       --help                                    value not yet valid, expected type str

Environment

• jsonargparse version: 4.27.1
• Python version: 3.11.7
• How jsonargparse was installed: pip install jsonargparse[signatures, omegaconf, argcomplete]
• OS: Linux (Ubuntu 22.04)
