--------------------------+-----------------------------
 Single use widgets, generated by `wp_register_sidebar_widget` and managed
 by `wp_register_widget_control` always return an "Invalid value" error in
 Customizer. They also block saving in Customizer.

 **We still can add them via appearance/widgets.php and go back to
 customizer.**

 Example to reproduce:

     {{{#!php
 <?php
 add_action('widgets_init', 'proof_of_concept_register_widget');
 function proof_of_concept_register_widget(){
     wp_register_sidebar_widget(
         'poc_widget',
         'POC Widget',
         'poc_widget_display',
         array(
         'description' => 'POC for Customize bug'
         )
     );
     wp_register_widget_control('poc_widget', 'poc_widget',
 'poc_widget_control');
 }
 function poc_widget_display(){
     echo '<p>POC for Customize bug</p>';
 }
 function poc_widget_control(){
     echo '<p>You should see a red notice "Invalid value" just above</p>';
 }


 }}}
