sidebar with an uppercase in id

[fantasyworld]

When I use "register_sidebar" with id include uppercase word. Like:

register_sidebar(array(
		'name'          => 'name',
		'id'            => 'sidezh_TW-1',
		'description'   => '',
		'before_widget' => '<div class="sidebar-outer">',
		'after_widget'  => '</div></div>',
		'before_title'  => '<h3>',
		'after_title'   => '</h3><div class="sidebar-content">',
	));

In the Widgets admin page, after I add a new widget in the sidebar area.
Reflash the Widgets admin page, the sidebar still had no widget.

This isn't really a "bug" - the codex says you can only use lowercase letters in your id's

​Function Reference/register sidebar

"id - Sidebar id - Must be all in lowercase, with no spaces (default is a numeric auto-incremented ID). If you do not set the id argument value, you will get E_USER_NOTICE messages in debug mode, starting with version 4.2."

Closing as wontfix. As per the Codex, the solution is to only use lowercase letters in your widget ID.
