wp_admin_css Filter Broken

[tech163]

I think the wp_admin_css filter is broken. I created a plugin with the following code, and nothing happens (I did activate it though).

function wp_admin_css_blah($test) {
	die($test);
}

add_filter('wp_admin_css', 'wp_admin_css_blah');

Core CSS files will get processed via WP_Styles, so the filter isn't very helpful anymore.

Look, I've fixed that adding the action hook to my template:

function my_wp_admin_css() {
 echo '<link rel="stylesheet" type="text/css" href="' .get_bloginfo('template_url').'/wp-admin.css">';
}

add_action('wp_admin_css','my_wp_admin_css');
apply_filters( 'wp_admin_css','my_wp_admin_css' );

If you call apply_filters() yourself, you might as well just call my_wp_admin_css() directly.

Please don't re-open this ticket.
