I can confirm that Alexey's example produces the unexpected result
on my system (bash 5.1), and that "shopt -s nullglob" has no effect
on it.
unicorn:~$ bash
unicorn:~$ x=("/"); for i in "${x[@]%/}"; do echo "i is '$i'"; done
unicorn:~$ shopt -s nullglob
unicorn:~$ x=("/"); for i in "${x[@]%/}"; do echo "i is '$i'"; done
unicorn:~$
