 It looks like WordPress is removing the '\' from a class name in the
 headers, this leads to difficulties making Oxygen to function with
 Multisite Language Switcher for instance.

 Here is what is done in Oxygen to integrate a widget:

 {{{#!php
 <?php
         $component_json = file_get_contents('php://input');
         $component              = json_decode( $component_json, true );
         $options                = $component['options']['original'];
 ...

         if (
 $GLOBALS['wp_widget_factory']->widgets[$options['class_name']] ) {
 ... do stuff
         }
         else {
                 printf( __("<b>Error!</b><br/> No '%s' widget registered
 in this installation", "component-theme"), $options['class_name'] );
         }

 }}}

 This does not work with multisite language switcher plugin since it is
 registered as "llocMslsMslsWidget" in $options and "lloc\Msls\MslsWidget"
 in $GLOBALS.

 I think it is a WordPress bug because there is no reason to register a
 class name without the '\'. Alternatively you may want to replace the '\'
 with '_' but then you'd have to do the same in
 $GLOBALS['wp_widget_factory']
