 I'm having a ton of issues using the admin (updating plugins, deleting
 themes), and they all appear to stem from commonL10n not being defined in
 the JS. Here are the errors I'm seeing in the console when I load any
 admin page:


 {{{
 jQuery.Deferred exception: commonL10n is not defined @https://example.com
 /wp-admin/js/common.min.js?ver=5.8:2:14762

 jQuery.Deferred exception: window.authcheckL10n is undefined
 @https://example.com/wp-includes/js/wp-auth-check.min.js?ver=5.8:2:433

 Uncaught ReferenceError: commonL10n is not defined: @https://example.com
 /wp-admin/js/common.min.js?ver=5.8:2:14762

 Uncaught TypeError: window.authcheckL10n is undefined:
 @https://example.com/wp-includes/js/wp-auth-check.min.js?ver=5.8:2:433
 }}}

 I did do some research and found that it appears commonL10n was removed?

 Was it really accidentally left in so many core files?
 I did upgrade my WP install from WP 5.4 to 5.8. Is it possible it didn't
 upgrade these files or something? And if so, perhaps the update procedure
 is broken?
