 [comment:9 From the next steps]:
 >A deeper investigative dive is needed into any impacted sites to better
 understand what's different on these sites.
 >* Is the object in GLOBALS['wp_locale'] an instance of WP_Locale?
 >* If yes, then search for where the properties are being reset.
 >* If no, look at the object's class code to determine how it presets the
 properties.

 >In some setups this has caused warnings from PHP 7.4 on:

 I did a deeper dive and still haven't been successful at replicating the
 issue or identifying if there's a deeper issue within Core itself. More
 information is needed to further investigate what's different in "some
 setups" that are causing the warnings.

 To confirm, @tyxla did [55047] solve the problem?
