Comment (by westonruter):

 [attachment:39103.1.dff] introduces a new `saving` property on
 `WP_Customize_Manager` and when it is set then the manager and any
 components should not call `preview` on the settings.

 The JS change fixes a related issue where emptying a nav menu location was
 assigning it to `NaN` as opposed to an empty value.
