testsuite does not pass with ruby3.5.0dev 2025-10-27 due to optional arguments behavior change??

With `ruby 3.5.0dev (2025-10-27 master 308fb9c8b4) +PRISM [x86_64-linux]` 
https://github.com/ruby/ruby/commit/308fb9c8b46f35cacfe7c62cd66776183cbdae1a

locale git head (  https://github.com/ruby-gettext/locale/commit/cf0d8c3207f22016340cd21601b32b07f040196a  ) testsuite does not pass like below.
Are there any optional arguments behavior change on ruby 3.5?? I am not sure.
