 I've noticed a change in localization behavior and was wondering if
 someone could point me to some documentation.

 I have a plugin, and in the plugin/captions directory are various .mo/.po
 files. There's an en_US file.

 A user in Australia has reported they are not getting captions. They're
 getting the Slug (mnemonic) value of the caption. I replicated the issue
 by setting the site language on my test environment to en_AU. I then
 created en_AU.mo/.po files, and the captions appeared.

 I'm a little surprised. I tried creating .mo/.po files without a language
 specifier, and those weren't picked up. I'm familiar with Java's method
 for ResourceBundles where it looks for bundle_lang_COUNTRY.properties,
 bundle_lang.properties, and finally bundle.properties? How is fallback
 handled in the case where there isn't a specific language_COUNTRY match?

 I did review this page:

 https://make.wordpress.org/core/2024/02/27/i18n-improvements-6-5
 -performant-translations/

 but it doesn't really seem on-point.

 Thanks for your help!

 George
