In order to avoid conflicts with other versions of this library, we are using a versioned body class in the format .sui-x-x-x where hyphens are replacing the periods of the current shared-ui package version. When using the shared-ui library in your plugin, make sure you are adding a body class with the same shared-ui version you are using.
add_filter( 'admin_body_class', 'admin_body_classes' );
function admin_body_classes( $classes ) {
$classes .= 'sui-2-12-25';
return $classes;
}
