Comment (by westonruter):

 @mdifelice I'm not sure I understand. If `wp_footer` is missing then what
 is executed once? The key thing you're needing to account for is whether
 or not the `keep-alive` messages are being sent from the preview to the
 pane. See https://github.com/WordPress/wordpress-develop/blob/4.8.0/src
 /wp-includes/js/customize-preview.js#L537-L595

 If `customize-preview.js` gets written out to the preview window (either
 via `wp_head()` or `wp_footer()`), then these messages will get sent and
 the Customizer will keep the `previewerAlive` state as `true`.
