While the code in _arrange.py does mark the unknown dock type branch as being for the benefit of type checkers only, and was marked as to be ignored for the purposes of coverage, it was still showing in a coverage test and it's not a terrible thing to ensure that a user, giving the wrong type of dock in their own code, will get the expected result.
