Comment:

 In [attachment:34738.1.diff]:

 * Add unit tests, including new assertions for
 `WP_Customize_Setting::preview()` for scalar, multidimensional, and custom
 types
 * Add unit tests for `WP_Customize_Manager::set_post_value()` and the
 related actions.
 * Add unit tests for ` WP_Customize_Widgets::call_widget_update()`.
 * Use `customize_post_value_set_{setting_id}` instead of general
 `customize_post_value_set` to
 clear_aggregated_multidimensional_preview_applied_flag.
 * Remove obsolete `WP_Customize_Setting::value()` call to
 `apply_multidimensional_preview_value()` call since now handled
 automatically via deferred-preview, and remove the new
 `apply_multidimensional_preview_value()` method since it is no longer
 needing to be called separately (due to deferred-preview being applied on
 `customize_post_value_set` action).
