 Hi,

 Steps to reproduce:

 code:

 {{{#!php
 <?php if(is_active_sidebar("custom-sidebar")) : ?>
     Sidebar is active, and it contains widget(s).
 <?php else: ?>
     Sidebar doesn't contain any widget.
 <?php endif;?>
 }}}

 1. Add a widget plugin to the `custom-sidebar`
 2. Disable the widget plugin
 3. Reload the page

 The page is still showing sidebar is active. and
 `wp_get_sidebars_widgets()` still contains the disabled plugin's widget
 info.

 Is this something intended? Or is it a bug?
