Comment:

 Problem(s) diagnosed:

 1. "admin-post" reference in components.min.js file missing from
 components.js file (happened on v5Beta4 upgrade)
 2. Bleeding edge builds do not package the /wp-includes/js/dist/ folder
 (which would have corrected issue1)
 3. {{{define( 'SAVEQUERIES', true );}}} in wp-config.php file causes
 JavaScript errors when browser debugging enabled

 --------
 NOTE:

 Not sure why {{{define( 'SAVEQUERIES', true );}}} would cause JavaScript
 errors when browser debugging is enabled since this setting affects the
 server. If it caused issues I would expect it to affect the delivered
 JavaScript whether browser debugging was enabled or disabled. Toggling the
 browser debugging would only affect the timing of the server requests not
 their substance. Thoughts?

 --------
 Actions:

 ME:
  - Downgrade Severity from Critical to Normal
  - Drop NeedsPatch tag
  - Drop ReporterFeedback tag

 @pento (or other core developer)
  1. Decide how best to handle this (close it? make it minor? make it
 enhancement? Add a note to the developer guide? etc)
  2. Consider enabling C.I. on bleeding edge releases so the /wp-
 includes/js/dist/ is updated and released in every build
  3. Consider why {{{define( 'SAVEQUERIES', true );}}} would cause
 JavaScript errors when browser debugging is enabled

 Thanks for all your help everyone. I'm glad this turned into a non-bug
 though it chewed up a chunk of my life that I would rather have back :-)
