body_class filter does not seem to work properly when using the filter

    Hi there,

    I need to add the name of the topmost product category as a css class to the <body> tag of the rendered pages. For that purpose i have this code in the functions.php of my theme:

    add_filter( 'body_class', 'wc_add_topmost_cat_name' );
function wc_add_topmost_cat_name( $classes ) {
    if(is_woocommerce()){
        global $wp_query;
        $q_obj = $wp_query->get_queried_object();
        $cat_id = $q_obj->term_id;

        $ancestors = get_ancestors($cat_id, 'product_cat');
        $ancestors = array_reverse($ancestors);

        $origin_ancestor = get_term_by("id", $ancestors[0], "product_cat");
        $origin_ancestor_id = $origin_ancestor->term_id;
        $origin_ancestor_name = strtolower($origin_ancestor->name);

        $classes[] = $origin_ancestor_name;
    }
    return $classes;
}

    Above code works as expected if i enter the URL of any of my product categories directly.

    However as soon as i click on any product categories in the filter generated by this plugin, the above code has no effect at all. After some digging in the code i found that if i comment out line 767 inside index.php ($wp_query->is_tax?=?false;), then i get the desired class name, but it also affects what product categories get rendered in the filter.

    There must be a way to add category names to the body class even if using this plugin to generate a category tree for navigation, but i simply can not figure it out. Any help is appreciated!
