Comment:

 [attachment:31294.diff] restores the auth behavior from 4.1, but even in
 4.1 it is still broken. Steps to reproduce:

 1. Log-in to Customizer
 2. Open WP Admin in another tab and log-out
 3. Go back to Customizer and try navigating around the preview.
 4. See preview window update with a login prompt.
 5. After logging-in, the whole Customizer will refresh with a Cheatin'
 message instead of allowing the user to continue using the Customizer as
 expected.
 6. Reloading the whole page then allows the Customizer to be used as
 expected, but after having lost all of their settings.
