 Replying to [comment:15 hptccharge]:
 > Replying to [comment:14 westonruter]: Sorry for delay in responding, I
 was out of the office.  Yes I was able to restore the bad CSS and as soon
 as you re-enable syntax highlighting, you lose the ability to edit/save
 the CSS. Using Firefox developer tools, I did not see any errors in the
 console. If I'm looking in the wrong place, point me to the tool that I
 should be looking at.  I've left one of my sites "broken" so I can retest
 this if needed.

 If you are comfortable getting me access to a site to test, you can create
 an admin user with the email trac-wp-core-42613 at xwp.co.

 > Note:  my theme developer (Customizr) who I had also reported this
 problem to, released an update that addresses it.

 So is it a theme compatibility problem with “Customizr” and not a core
 issue then?
