As I understand it, -N stands for NEW and therefore should return a true

FWIW, there's some disagreement on this.
Not very much.

Yes, this is the substance of the bug report. That version of the bash
builtin `test', which is around 15 years old, did it wrong. It was
finally fixed in bash-5.1.
% /opt/local/bin/bash -c 'echo "$BASH_VERSION"; . ./foo_test'

% ksh -c 'echo "${.sh.version}"; . ./foo_test'
