nested links in class-perfect-woocommerce-brands.php

Hi, function show_brands_in_loop()

public static function show_brands_in_loop() {
		$brands_in_loop      = get_option( 'wc_pwb_admin_tab_brands_in_loop' );
		$image_size_selected = get_option( 'wc_pwb_admin_tab_brand_logo_size', 'thumbnail' );

		if ( $brands_in_loop == 'brand_link' || $brands_in_loop == 'brand_image' ) {

			global $product;
			$product_id     = $product->get_id();
			$product_brands = wp_get_post_terms( $product_id, 'pwb-brand' );
			if ( ! empty( $product_brands ) ) {
				echo '<div class="pwb-brands-in-loop">';
				foreach ( $product_brands as $brand ) {

					echo '<span>';
					$brand_link    = get_term_link( $brand->term_id, 'pwb-brand' );
					$attachment_id = get_term_meta( $brand->term_id, 'pwb_brand_image', 1 );

					$attachment_html = wp_get_attachment_image( $attachment_id, $image_size_selected );
					if ( ! empty( $attachment_html ) && $brands_in_loop == 'brand_image' ) {
						echo '<a href="' . esc_url( $brand_link ) . '">' . wp_kses_post( $attachment_html ) . '</a>';
					} else {
						if ( $brand !== $product_brands[0] ) {
							echo wp_kses_post( get_option( 'wc_pwb_admin_tab_brands_in_loop_separator', '' ) );
						}
						echo '<a href="' . esc_url( $brand_link ) . '">' . esc_html( $brand->name ) . '</a>';
					}
					echo '</span>';
				}
				echo '</div>';
			}
