The change LGTM but I didn't approve the PR since I don't know well argparse code base. The test covers the changed code.
I'm not sure if we should backport the change since it changes the behavior which is there since Python 3.8. Even if it's a bug, users may rely on the current behavior.

I think this is pretty safe change. It makes the code working as it is supposed to work, as it is documented, and as it worked it the past. If you do not want to disallow abbreviation, just do not use |
