Comment:

 In [attachment:36944.1.diff]:

 * Export setting validities with full refreshes and selective refreshes,
 giving near immediate feedback for validation errors.
 * Introduce `WP_Customize_Manager::prepare_setting_validity_for_js()`.

 The UX should be so much better to show/hide notifications for server-side
 setting validation handling.

 @fjarrett @mrahmadawais @aristath @natewr would one or more of you please
 test?
