When known and unknown options are given together in the same option string (e.g. -xy) then ArgumentParser behaves in a strange way:

- if the known option is given first (so -k is known and the parser is fed with ['-ku']) then the parsing aborts with "error: argument -k/--known: ignored explicit argument 'u'"

- if the unknown option is given first then both options are treated as unknown and returned in the list of remaining arguments.

This makes it impossible to use parse_known_args for its intended purpose because every single letter option might be interleaved with other unknown options.

I attached a test script that demonstrates this.
